History BLAM / AnimeAndManga

* The ending of ''Anime/AstroGanger''. [[spoiler: Ganger bids his farewells to Kantaro and orders him to enter his saucer - and then tears through the Blasters' base, allowing the panther to kill them all. Then, Ganger throws the panther against the walls, knowing that for the sake of the Earth it can't live. However, due to all the energy it absorbed, it sets off a reaction that causes the entire ship to explode. Poor Ganger looks aghast at the rubble as he accepts his death. Meanwhile, Kantaro and Rie watch from their ship, which is slowly entering Earth, crying. Then the anime straight up cuts to the credits, without giving the audience the chance to digest [[TheHeroDies what just happened]].]] In Syria, this episode actually caused audiences to cry.

* ''Anime/{{Doraemon}}'' isn't above having weird moments like these in the movies:

** In episode 12, L is listening to a message from the second Kira, which at one point refers to {{shinigami}}. Upon hearing this word, the normally unflappable L suddenly has a [[https://www.youtube.com/watch?v=MwFszVk_QRw ridiculously over-the-top panic attack]]. It's never explained why the mention of "shinigami" would upset him so much.

*** The Dark Ocean storyline visited in the episode was originally planned to see expansion, but this was scrapped due to meddling from Bandai and disputes amongst the writing staff.

*** Though, interestingly, the Dark Ocean and Daemon episodes are generally [[Administrivia/TropesAreTools pretty well-regarded.]]

** In an episode of Z, while he's training with Piccolo, Gohan falls down a cliff, tries and fails to get back up...and then starts shouting out Shiritori words. Notably, each and every English dub of this scene has that moment completely rewritten, presumably because of how nonsensical and untranslatable it is.
** Vegeta's desire to take over the Earth and fighting with Gohan after finding out that both Goku and Freeza had (apparently) died. It's a complete non-sequitur (it's anime-only filler that doesn't occur in the manga), it's odd considering that Vegeta later said that he actually wants to see Goku alive and it's never mentioned again, Gohan is seen in the next episode uninjured and Vegeta, who flew off, is standing exactly where he was in the previous episode, also uninjured.
** The crossovers episodes with ''Manga/DrSlump'' are the very definition of this, coming off as completely out of place episodes in the middle of the current story arc. Even ignoring the story arcs, they still feel out of place for the Dragon Ball universe, given the zaniness and quirkiness of Penguin Village, not to mention [[RobotGirl Arale's]] insanely overpowered gag power (even inexplicably surpassing the power level of robots specifically designed for combat like Cell, as least going by filler in ''Anime/DragonBallSuper''), to the point you would be forgiven for thinking that Goku had somehow been transported to another dimension. The fact that her powers are attributed to her being a gag character makes her even more of a BLAM for the franchise.

* The very first episode of the ''Literature/FullMetalPanic'' anime features Sousuke rescuing a unknown but relevant-looking girl, whom light novel readers would recognize as Mira Kudan, a fellow Whispered, but given that she never appears again in the entire anime series, for people unfamiliar with the novels she ends up being an unexplained, out-of-context plot point LeftHanging. This only finally changed when Mira returned in the ''Invisible Victory'' season, which premiered ''sixteen years'' after her anime debut.

* There is an early episode of ''Anime/DigimonAdventure02'' that, although comedy-driven and not supposed to be taken seriously, has a pretty jarring scene. Simply putting, V-Mon all of a sudden admits having romantic feelings for Tailmon and decides to train hard to evolve and impress her. It's a ''very'' strange scene, mainly because in the ''Franchise/{{Digimon}}'' series (especially the ''Adventure'' continuity) almost no Digimon ever show romantic affection for other species of Digimon. And of course, this affection was never even hinted before, and it's never mentioned later.

* An early chapter of ''Manga/{{Hellsing}}'' features Seras sleeping in a coffin after it was transported to Brazil. Before Alucard tries to wake her up, she breaks into a bizarre dream about her gun having the spirit of [[Franchise/{{Dune}} Baron Harkonnen]] that talks to her. As the scene keeps going, the art eventually devolves into random scribbles that only sort of look like humanoid shapes before Alucard eventually gets her up. The OVA has an equivalent sequence involving Alucard and a lot of spirits, most notably a Bruce Willis spirit. Seras' gun is named Harkonnen and Alucard's is Jackal.

* In a movie that's already one hell of a MindScrew, the brief moment in the ''Anime/RevolutionaryGirlUtena'' movie when the strange, offbeat and surreal video of Nanami the cow is put in by the shadow girls manages to be one of these, coming right after a dramatic and horrifying scene, and of course never being mentioned again. Of course, according to Kunihiko Ikuhara, this was intentional. He's just that sort of guy. While the scene is so weird that even the shadowgirls are speechless, the video is kind of foreshadowing. If you think of Chuchu as Utena, The crocodile thing as Shiori and Nanami the cow as Akio... It makes sense if you think of the entire movie being on acid, but when even ''the characters'' are going "What the hell?!" in Utena you know it's something special.

** And the show is just as bad. Seemingly every Nanami episode includes bizarre examples of this, including escaped boxing kangaroos, surfing elephants, a designer-brand cowbell that turns its wearer into a cow, and girls mysteriously laying eggs.

* In the 1990's anime adaptation of ''Literature/TheMoomins'', the episode "Crooks in Moominvalley" has the infamous scene where Little My asks Snufkin out on a date, causing him to panic and fall into the water. Little My has never shown romantic interest in Snufkin before, it makes no sense for her to want to date Snufkin since [[BrotherSisterIncest they're related]], and this ends up having no bearing on the rest of the episode (with the only acknowledgement that it even happened being one scene where Snufkin briefly looks nervous and tries to hide when he sees Little My running towards him).

* ''Manga/BoboboboBobobo'': being a series that [[WidgetSeries is nothing but BLAMs]], one stands out in particular, where Beauty, the OnlySaneMan of the group, suddenly snaps and begins playing along with the weirdness for no reason, once Bobobo and Don Patch get back on screen and do something strange, she's right back to normal, no explanation given, no comments made.

* ''Anime/{{Daimos}}'': In episode 39, [[TheCreon Georiya]] [[https://ibb.co/48DbByj shoots an arrow]] at the [[UsefulNotes/{{Judaism}} Star Of David]]. It is never explained why this [[AngelicAliens Baamite alien]] has a specific grudge against the Jewish people and feels a need to deface their religious symbols, considering that up to this event, the anime never mentioned Judaism before or made references to it. Prior episodes establish that Georiya despises the human race and wants to wipe them out, so him focusing on one group in particular comes off as very absurd.

* In the bonus story of ''LightNovel/{{Haganai}}'' volume 7, Yozora hits Maria on the cheek and quotes the part of the Bible where Jesus talks about turning the other cheek. As she does, the statue of Jesus in the same room comments that he never said that. Up until this point there hasn't been any supernatural elements in the series.

* ''LightNovel/HeavyObject'' has an almost perfect example. During a firefight between the protagonists and the enemies in Antarctica, a baby penguin wanders into the battlefield. Both groups stop shooting at the exact same time, to avoid harming it, and they start to silently cheer for the penguin. Then, an albatross appears and tries to attack the penguin, but the penguin's mother appears and engages in a staredown to protect her baby. Eventually, the albatross gives up. Both groups cheer loudly, shoot into the air and end up scaring the penguins. After they go away, the firefight restarts like nothing had happened.

* Near the end of the sixth episode of ''LightNovel/KureNai'', all the characters (who are currently practicing for a play) suddenly burst into a seemingly-improvised song--out of ''nowhere''--that has nothing to do with the play. (For one thing, all the names in the song are English, while the play is Japanese). The song goes on for a surprising amount of time before it stops, confuses everyone watching on, and just sort of... ends there.

* In Episode 2 of ''Kimihagu'', Emily has ADateWithRosiePalms in the bathroom, but's it's never brought up again at all. The anime producers must've figured that since she ''did'' have a route and proper sex scenes in the main HGame with the main protagonist (just like all the other girls), this would've been better than nothing.

* ''Manga/{{Phoenix}}'': In the first volume, "Dawn", before Saruta and Nagi take on a pack of wolves, there's a brief sequence depicting the wolves in [[ExtremeCloseUp action star style]], [[KabukiTheatre kabuki style]], [[{{Disneyesque}} Disney style]], [[MotionBlur grand prix style]], [[ChorusGirls broadway style]] and [[WavingSignsAround student riot style]]. Of course, once the gag's over, the story just keeps going like nothing happened.

* ''Anime/DoraemonNobitaAndTheGalaxySuperExpress'' have Doraemon and Nobita spending their first night in the titular Express, only for Nobita to run into a MirrorScare involving a vampire. Later on Nobita gets attacked by an outlaw, Suneo finds a pirate in his bedroom, and Gian have a '''dinosaur''' bursting through his windows... all events which are later swept aside when the story decide to focus on an AssimilationPlot involving alien parasites instead.

* ''Anime/{{Legend of Galactic Heroes}}'', of all things, manages to get one in early in its second season, in the form of a bizarre sequence where Reinhard and Kircheis turn into angels and fly away into the sunset. It lasts all of five seconds, comes out of nowhere right during the middle of another character's speech, and has absolutely no bearing on the plot at hand (Reinhard and Kircheis both remain firmly on [[spoiler:and in the latter's case, ''in'']] the ground afterwards).

*** The most prominent time the Dark Ocean is mentioned again is when Daemon is sealed in it. Speaking of Daemon, he's another example. He's extremely powerful villain that has no connection to the events of the main story shows up with no explanation for what he is or where he came from that nearly decimates the protagonists, and isn't mentioned again.

* ''Manga/OnePiece'' Creator/EiichiroOda very good at subverting this trope. Many events that might ''appear'' to be a Big Lipped Alligator Moment at first in fact turn out to be a ChekhovsGun for much later. Oda also subverts this trope by making all these seemingly random moments so [[RuleOfCool ridiculously absurd]] that the audience just goes along with it. But some moments just are bizzare even by ''One Piece'''s standards
** This [[https://www.youtube.com/watch?v=Fh9m9un744w disco zombie dance number]] in ''Manga/OnePiece''. There is no lead up beyond zombies shuffling to a mansion carrying a disco ball, and no mention of it ever made again, though the dance hall is mentioned as a possible location for a wedding reception later in a one-off gag. The entire arc is a play on Music/MichaelJackson's songs and videos -- the name Thriller Bark (''Thriller''), Brook the skeleton's 45-degree angle pose joke (Smooth Criminal), and the aforementioned dancing zombies (disco dancing, but sadly not the music). The dance sequence was originally intended to be a more direct parody of ''Thriller'' (with similar music and dance moves) but [[ExecutiveMeddling someone in the legal department got worried about the potential for a lawsuit]] so the bit was changed to a far more generic number, which makes the whole thing seem random and out-of-place.
** During the Alabasta arc, there was the arrival of the Tsumegeri Guards, 4 [[RedShirt Red Shirts]] that suddenly show up with no prior buildup whatsoever. They drink the Hero Water, which gives those who drink it tremendous strength, but results in instant death after 5 minutes. They try to attack Crocodile, who changes into sand, flies to the roof of a building, and mocks them while waiting for their deaths. Needless to say, they die shortly afterwards and despite how upset Vivi, Cobra, and Chaka were about this, it's never mentioned again. This scene did nothing to further the arc's plot. It ''does'' point out how petty Crocodile can be if he wants, setting his character for future fights with Luffy.

* ''Anime/ChouKuseNiNarisou'' has a recurring character, Momoko, whose entire purpose is seemingly to appear out of nowhere, do something completely bizarre, and then leave.
