History AbortedArc / MarvelUniverse

** Likewise, despite "Cold Comfort" having Cyclops and Havok puzzled by each other, including their powers not working, nothing is done with their rivalry or even that they're brothers.

* ''WesternAnimation/AvengersAssemble'' Season 2 ended with ComicBook/CaptainAmerica and ComicBook/IronMan deciding that they needed to expand the team in order to face bigger threats, and the last shot showed them looking at images of a bunch of potential new recruits like ComicBook/BlackPanther, [[ComicBook/CarolDanvers Captain Marvel]], ComicBook/DoctorStrange, and ComicBook/MoonKnight. The Season 3 premiere then opened up with none of these characters as part of the Avengers roster, with ComicBook/TheFalcon offhandedly mentioning that the expansion plan had been canceled. Later episodes did however find ways to incorporate some of the new recruits, but not in the original plan: they were part of a government sponsored team, then later filled in for the original Avengers when they disappeared.

** "The Unstoppable Juggernaut" ends with Comicbook/{{Colossus}} declining an offer to join the team and saying that he intends to travel the country to find [[ComicBook/{{Magik}} Illyana]], his missing little sister. The next time Colossus shows up, he's still in New York, and Illyana is safely in Russia with their parents. There's no further mention of her supposed disappearance, and nothing to indicate she's ever even ''been'' to America.
** In the second episode of the "Beyond Good and Evil" arc, Comicbook/{{Apocalypse}} is able to keep Comicbook/{{Magneto}} in line by promising to resurrect his dead wife. This is never brought up again, and a later episode of the same storyline instead offers a completely different explanation for why Magneto chose to work for Apocalypse.

* In ''Beyond!'', Creator/{{Dwayne McDuffie}} killed off the teen hero Gravity by having him perform a HeroicSacrifice. However, the final panel of the book hinted that this wasn't the end of Gravity's tale. The character was later resurrected in [=McDuffie=]'s ''Fantastic Four'' run, but hasn't really done anything of note since. It turns out that this is because the original plan was to resurrect Gravity and have him become the new ComicBook/{{Captain Marvel|MarvelComics}}, but someone else decided it would be a better idea to introduce a Skrull posing as the original Captain Marvel in ''ComicBook/CivilWar'' instead.

* The first ''VideoGame/MarvelUltimateAlliance'' ended with a SequelHook where ComicBook/{{Galactus}} was revealed to be planning a strike against Earth. This was completely ignored in the sequel in favor of an adaptation of the ''Comicbook/CivilWar'' storyline, with Galactus' planned attack [[SecondHandStorytelling only mentioned in passing]].

* ''WesternAnimation/TheAvengersEarthsMightiestHeroes'': Due to being canceled after only two seasons, the show had a few of these. Notably, the heavily foreshadowed showdown with Surtur and the Enchantress never took place, and Maria Hill's repeated rants about a [[Comicbook/CivilWar Superhuman Registration Act]] never panned out.

* Creator/GerryDuggan's ''ComicBook/{{Hulk|2014}}'' run ended before the plot about Gammon, Banner's [[AIIsACrapshoot evil A.I.]], could reach any sort of meaningful resolution. Earlier in the same run, there was also {{Foreshadowing}} for a confrontation between Doc Green and CharactersKangTheConqueror. The anticipated fight never happened.

* During the ''ComicBook/Inferno1988'' crossover, Mister Fantastic and the Invisible Woman helped form a new team of Avengers in a manner similar to the formation of the original team way back in ''ComicBook/TheAvengers'' #1. Despite clearly being positioned as major players in the new team, they were quickly written out of the book once ''Inferno'' ended. It turns out that this is because Creator/WaltSimonson had been given permission to add the two to the Avengers, only for editorial to change their minds and decide they wanted them back in the ComicBook/FantasticFour instead.

* Happened a lot in earlier issues of ''ComicBook/DoctorStrange'', when writers were struggling to figure out how the titular character fit into a superhero universe. In one issue Strange is suffering from financial difficulties due to a lack of income, and considers taking on mundane jobs, such as a stage magician, to earn a living. Not two issues later Wong confronts hom about their ongoing fiscal hardships only for Strange to conjure a giant stack of money out of thin air.

** A battle with Nightmare over a sleeping Eternity destroyed the entire planet Earth and everyone on it. As a token of appreciation for saving him, Eternity rewards Strange by creating a new Earth separate from but identical to the one that was just destroyed. Strange spends a number of issues grappling with the implication that he is the only "real" person left on a planet full of clones, and it drives him to the brink of insanity in a few stories. This subplot would later be abruptly dropped, with all its implications swept under the rug and dismissed as the work of some kind of illusion.

* Creator/DanAbnett's ''ComicBook/GuardiansOfTheGalaxy2008'' run had the modern Guardians meet the [[TimeTravelTenseTrouble classic/future]] Guardians from the year 3000, who are shocked to see Jack Flag and declare him to be the "chosen one". This was never followed up on as Jack was whisked to ComicBookLimbo following the end of the series until he was brought BackForTheDead in Nick Spencer's ''Captain America'' run.

** ''Film/{{The Incredible Hulk|2008}}'':
*** This movie's [[StillbornFranchise poor box-office returns]] created a big one involving [[MadScientist Dr. Samuel Sterns]] and his StartOfDarkness. Though the studio was able to continue Bruce Banner's character arc with his appearance in ''Film/{{The Avengers|2012}}'', the lack of direct sequels to ''The Incredible Hulk'' meant that we never got to see the fallout from [[spoiler:Sterns using Banner's gamma-irradiated blood to turn himself into the Leader]]. This plot thread was [[AllThereInTheManual eventually continued]] in the ''[[ComicBook/TheAvengersPreludeFurysBigWeek Fury's Big Week]]'' comic that was released as a prequel to ''The Avengers''. In it, [[spoiler:Sterns uses his new abilities to attack Black Widow, only to end up knocked out and taken into custody by ComicBook/{{SHIELD}}.]]
*** The even bigger plot thread was the final scene that showed Thunderbolt Ross partnering with [[Film/IronMan Tony Stark]] to take down the Hulk. This was never mentioned in any of the subsequent films. [[OnceMoreWithClarity This was explained]] in the short film ''Film/TheConsultant''; S.H.I.E.L.D. sent Tony as a patsy to ruin the relationship with Ross after the World Security Council ordered Fury to add the Abomination to the roster of the Avengers.
** ''Film/CaptainAmericaTheWinterSoldier'' seemed to be hinting at a romance between Steve Rogers and [[ComicBook/{{Agent 13}} Sharon Carter]], with the two even kissing in the sequel, ''Film/CaptainAmericaCivilWar''. This element was dropped in subsequent films, with Sharon not even appearing (or even getting mentioned by name) in ''Film/AvengersInfinityWar'' or ''Film/AvengersEndgame''. While Sharon does reappear in ''Series/TheFalconAndTheWinterSoldier'', the fact that the series instead focuses on [[LegacyCharacter the new Captain America]] and Steve never appears means that the romance plot is never picked up on.
*** Both in-universe and a meta example, despite it being a trademark of his backstory and one of the reasons the army is in the supersoldier business, Steve doesn't actually fight any Nazis, just in films and comic books. Justified since by the time he gets sent overseas and begins to take part in the war, Schmidt and HYDRA are much larger threats. Although his Smithsonian exhibit in ''The Winter Soldier'' shows that the Howling Commandos did offscreen missions against non-HYDRA soldiers.
** The New Avengers at the end of ''Film/AvengersAgeOfUltron'' were hyped up as a replacement roster because of Tony retiring, Hulk going missing and Thor leaving to look for the Infinity Stones. They proceeded to do one onscreen mission in ''Civil War'' which lead to the eponymous conflict and then quietly disappeared until ''Film/AvengersInfinityWar'' 3 years later.
*** Thor's AchillesInHisTent storyline does get a resolution when [[spoiler:he comes back claiming to have had "a vision"]] but what was meant to be a longer storyline ended up mainly a MissingTrailerScene.
*** The Maximoff twins have a major subplot involving them seeking revenge on Tony Stark for killing their parents. There's no real resolution to this, as they only side with the Avengers because they realize Ultron is an even greater evil, not out of any real epiphany about Tony not being such a bad guy.
*** Thor's vision of Asgard was supposed to setup ''Film/ThorRagnarok''. Depictions of the Asgardians descending into decadence, demonic musicians, and Heimdall being blinded were all meant to foreshadow the events of the upcoming film. Once Creator/TaikaWaititi was brought onboard as the film's director, ''Ragnarok'' underwent a complete ToneShift and much of the imagery seen in Thor's vision went unused.
** ''Film/AntManAndTheWasp''
*** Shortly after Ghost reveals Hank Pym's role in her father's death, Hank defends himself by claiming that Elihas was a traitor who deserved to be fired, for reasons he doesn't elaborate on. There is no followup or clarification on this later on -- it never gets brought up again.
*** HYDRA agent Mitchell Carson got Pym particles in ''Film/AntMan1''. If he ever used them, it has never been addressed.

* Simon Spurrier wrote a companion miniseries to Jason Aaron's ''ComicBook/GhostRider'' run titled ''Ghost Rider: Danny Ketch''. It was basically used to explain why the second Ghost Rider was suddenly a very evil acting WellIntentionedExtremist working for Zadkiel. One of the characters introduced was Mary Le Bow, Danny's confidante and occultist friend. She's "killed" at the end of the story, but her soul ends up in a sort of limbo, where her murderer resides. He says he'll find her a new body and that magic users like her are going to be facing a nebulous threat separate from the war in Heaven that the Ghost Riders were waging. This isn't followed up on, and the following ''Ghost Rider'' series introduces an entirely new Ghost Rider at that. Danny Ketch himself never mentions Mary again and would wind up in comic book limbo.

* ''ComicBook/TheIncredibleHercules'' had a subplot where ComicBook/AmadeusCho visited his deceased family in the afterlife, only to discover that his little sister, whom he had presumed dead as well, was actually still alive. Maddy Cho did finally appear years later in ''ComicBook/TotallyAwesomeHulk'', but her actual reunion with Amadeus apparently took place entirely offscreen.

* Gerry Duggan's ''[[ComicBook/IncredibleHulk Hulk]]'' run ended before the plot about Gammon, Banner's [[AIIsACrapshoot evil A.I.]], could reach any sort of meaningful resolution. Earlier in the same run, there was also {{Foreshadowing}} for a confrontation between Doc Green and Kang the Conqueror. The anticipated fight never happened.

** There were plans for sequels, and at least some plot points were meant to be expanded upon in them. Due to the film's [[BoxOfficeBomb box office failure]] and the sequels being canceled, it's unlikely they'll get any kind of payoff.

** Reginald Hudlin's first run ended with [[Comicbook/{{Killmonger}} Erik Killmonger]]'s son swearing vengeance against T'Challa after watching ComicBook/MonicaRambeau kill his dad. The son hasn't been seen since then, and his planned revenge has yet to occur.

[[OnceMoreWithClarity This was explained]] in the short film ''Film/TheConsultant''; S.H.I.E.L.D. sent Tony as a patsy to ruin the relationship with Ross after the World Security Council ordered Fury to add the Abomination to the roster of the Avengers.

* At the end of the first arc in ''[[ComicBook/TheInvadersMarvel All-New Invaders]]'', ComicBook/TheEternals discovered a comatose ComicBook/{{Galactus}} in the Negative Zone (where he'd been trapped following ''ComicBook/CataclysmTheUltimatesLastStand''), and planned to use the Gods' Whisper to control him and make him destroy the Kree. The planned attack on the Kree never occurred, and Galactus later appeared without any reference to how he'd escaped the Negative Zone.

** "The Unstoppable Juggernaut" ends with Comicbook/{{Colossus}} declining an offer to join the team and saying that he intends to travel the country to find Comicbook/{{Illyana|Rasputin}}, his missing little sister. The next time Colossus shows up, he's still in New York, and Illyana is safely in Russia with their parents. There's no further mention of her supposed disappearance, and nothing to indicate she's ever even ''been'' to America.

** Reginald Hudlin's first run ended with ComicBook/ErikKillmonger's son swearing vengeance against T'Challa after watching ComicBook/MonicaRambeau kill his dad. The son hasn't been seen since then, and his planned revenge has yet to occur.

* In ''Beyond!'', Creator/{{Dwayne McDuffie}} killed off the teen hero Gravity by having him perform a HeroicSacrifice. However, the final panel of the book hinted that this wasn't the end of Gravity's tale. The character was later resurrected in [=McDuffie=]'s ''Fantastic Four'' run, but hasn't really done anything of note since. It turns out that this is because the original plan was to resurrect Gravity and have him become the new ComicBook/{{Captain Marvel|l}}, but someone else decided it would be a better idea to introduce a Skrull posing as the original Captain Marvel in ''ComicBook/CivilWar'' instead.

** ''Film/TheAmazingSpiderMan2'': It seems the arc from the first movie of Peter hunting Uncle Ben's killer has been dropped, despite it being a SequelHook last time.
