* In ''WesternAnimation/SpiderManAcrossTheSpiderVerse'', ComicBook/MilesMorales notably has a different last name than his father, Officer Jefferson Davis. When Miles was originally introduced in ''[[ComicBook/UltimateSpiderMan Ultimate Comics: Spider-Man]]'', this was because "Jefferson Davis" was only his father's ''birthname''; he took his wife Rio Morales' last name after he got married, wanting to distance himself from his criminal brother Aaron Davis. But since this isn't the case in the film, it raises the question of why "Davis" isn't Miles' last name too.

* Just like the original ''ComicBook/{{Flashpoint|DCComics}}'' comic, ''[[WesternAnimation/JusticeLeagueTheFlashpointParadox Justice League: The Flashpoint Paradox]]'' ends with Franchise/TheFlash [[spoiler:rebooting history and inadvertently bringing about the Comicbook/{{New 52}} timeline]]. However, this makes no sense, as in the original comic, the New 52 timeline was brought about when Pandora tricked Flash into merging Franchise/TheDCU timeline with the Creator/{{Vertigo|Comics}} and Creator/{{Wildstorm}} timelines. [[AdaptedOut Since neither Pandora nor the timeline merger sequence were present in the film]], it's left completely unexplained as to why the Flash and Franchise/{{Batman}} are suddenly wearing their New 52 costumes at the end of the film.

* In ''ComicBook/TheSmurfs'' original comic books, it has been established that [[GrumpyBear Grouchy Smurf]] was the Smurf who was bitten by the Bzz Fly in "[[ZombieApocalypse The Black Smurfs]]", and his current moody behavior was caused by this (either due to having been more time as a Black Smurf as the others, or because he was directly stung by the fly, while the others were bitten by their infected peers). The Hanna-Barbera AnimatedAdaptation had several episodes that included Grouchy Smurf (as grouchy as ever) before adapting this story into "The Purple Smurfs", so his behavior is unexplained. It cannot even be excused by AnachronicOrder, since Lazy Smurf is the one bitten by the Purple Fly, and it's shown later when Grouchy Smurf is bitten by a Purple Smurf, even telling at mid-transformation "[[MadLibsCatchPhrase I hate...]] [[SubvertedCatchPhrase GNAP!]]"

** In the original, Scar's plan was to have Simba and Mufasa's deaths look like they died in a stampede. Simba's survival was an accident, so Scar tricked Simba into thinking he caused it, which considering it happened after Simba started practicing roaring at Scar's vague suggestion, made it understandable Simba would think he caused it and feel enough guilt to run away. The remake keeps this mostly the same, except it has Scar bring Simba to the valley for the explicit purpose of practicing roaring before he has the hyenas cause the stampede, which makes Simba's guilt no longer make sense since Scar basically told him to do it, and also makes it seem like Scar wanted Simba to survive, since there was no reason to make him seem like he caused it.

* ''Fanfic/ABrighterDark'' [[AdaptedOut removes]] [[GreaterScopeVillain Anankos and the kingdom of Valla]] from the narrative. The problem is, a lot of character motivations and backstories (most notably Garon's]] only make sense with Anankos's involvement, meaning quite a bit of the fic (which [[StationsOfTheCanon follows canon very closely]]) doesn't make sense.

* [[TheHeavy Cinder Fall's]] backstory in ''WebAnimation/{{RWBY}}'' is a WholePlotReference to the Cinderella fairytale but transplanting the classic story into the pre-established world of Remnant and other alternations create two serious [[FridgeLogic logical holes.]] In most versions of the story, Cinderella is made responsible for all the housework in her family manor that, while large, has only a few people in it, while here, Cinder appears to be [[OddlySmallOrganization the only staff in a hotel]] that looks like it could hold dozens if not hundreds of guests. Slavery is also explicitly illegal in Remnant [[note]] Cinder is forced to do menial labor in a business and [[ElectricTorture physically tortured as punishment]] so Madam being her legal guardian makes the difference between her condition and traditional slavery a rather obvious DistinctionWithoutADifference and a massive loophole it beggars belief Ozpin and his allies who outlawed slavery could overlook [[/note]] so the Prince Charming analogue in Cinder's backstory, a sympathetic huntsman named Rhodes, seems TooDumbToLive by deciding to help her by training her to be a huntress for the next several years [[JustEatGilligan instead of calling the police or social services.]] The possibility of him doing that, or taking her away to a better orphanage or family himself, is not even mentioned. In almost every other telling, the Prince has no idea the hell Cinderella is living in, and the "ascension" he offers, marriage into royalty, is something that can be done almost instantly.

** In the original, Scar knocks Zazu unconscious before he can go find help during the stampede, removing the only witness from the situation. In the remake, Scar instead orders Zazu to go retrieve the pride for help. After the stampede, Scar claims he didn't make it to the gorge in time to save Mufasa and Simba - even though Zazu was with him at the gorge. Considering Zazu still regularly visited Pride Rock after Scar became king (despite being implied to have been banished), and is also implied to have heard every word of Scar announcing himself as king, it's a glaring flaw in Scar's cover story.

* [[TheHeavy Cinder Fall's]] [[FreudianExcuse backstory]] in ''WebAnimation/{{RWBY}}'' is a WholePlotReference to the Cinderella fairytale but transplanting the classic story into the pre-established world of Remnant and other alternations made cause it to not make sense. In most versions of the story, Cinderella is made responsible for all the housework in her family manor that, while large, has only four people in it, while here, Cinder appears to be [[OddlySmallOrganization the only staff in a hotel that looks like it could hold dozens if not hundreds of guests.]] The world of Remnant is also established to have already had western-like laws and values (at least on paper) by that point in time, but the best solution the Prince Charming analogue in Cinder's backstory, a sympathetic huntsman named Rhodes, can think of for a girl who is enslaved and [[ElectricTorture tortured]] by her guardians is to train her to be a huntress, instead of [[SocialServicesDoesNotExist calling the police or social services.]] Said plan will also require Cinder to live with her guardians for several more years while she trains, even though Rhodes should easily be able to take her away to a better orphanage or family himself. In almost every other telling, the Prince has no idea the hell Cinderella is living in, and he still tries to marry her as soon as they meet.

* In the ''WesternAnimation/ThomasAndFriends'' episode "Trucks!", some trucks (not road vehicles, but what Americans would call freight cars) deliberately cause an accident because they think Peter Sam is Sir Handel, despite Peter Sam being painted green and Sir Handel being painted blue. This made more sense in the original Railway Series book, where all the Narrow Gage engines were painted the same gray color.

If this is caused by a work being translated into another language, it's a DubInducedPlothole. If there is simply a lack of explanation as to why something happened, instead of a full-on PlotHole, it's AdaptationExplanationExtrication. Contrast AdaptationalExplanation where a plot hole gets fixed in an adaptation.

** In the [[WesternAnimation/TheLionKing1994 original film]], it's made fairly clear why the hyenas are so willing to go along with Scar's plan: they're a bunch of bickering louts with no leader, he's able to bribe them with food, he's responsible for their initial attack on Simba and rewards them even after they fail, and based on the way they speak to him, it seems like they've known each other for a while. In the remake, it's made clear that Scar only met the hyenas after said attack, he doesn't offer them anything apart from his word, and the hyenas already have a clear leader in the form of an AdaptationalBadass-ified Zira. Yet the hyenas are still happy to fall in line for a very risky plan, based on the statements of the brother of the guy who just ripped through them like tissue paper. If anything, it makes one wonder why the hyenas didn't try to attack Scar the moment he showed up.

* ''TabletopGames/{{Pathfinder}}'': Second Edition has a really odd and [[ExggeratedTrope extreme]] example. They decided to just retroactively remove slavery from the game, not just in the sense of not allow pcs to own slaves (which would be completely reasonable), but making it so even ''villains'' don't have slaves. This creates tons of plotholes, as there were a lot of evil races, organizations, and countries that use slavery, and there's even a species of demon created from slavers. There are also multiple organizations dedicated to abolishing slavery, so what they are supposed to do now is a mystery.

* The 2019 remake of ''[[WesternAnimation/TheLionKing2019 The Lion King]]'' gets a major one regarding Scar and Zazu. In the [[WesternAnimation/TheLionKing1994 original film]], Scar knocks Zazu unconscious before he can go find help during the stampede, removing the only witness from the situation. In the remake, Scar instead orders Zazu to go retrieve the pride for help. After the stampede, Scar claims he didn't make it to the gorge in time to save Mufasa and Simba - even though Zazu was with him at the gorge. Considering Zazu still regularly visited Pride Rock after Scar became king (despite being implied to have been banished), and is also implied to have heard every word of Scar announcing himself as king, it's a glaring flaw in Scar's cover story.

* ''VideoGame/BatmanArkhamAsylum'': Subverted. There are small hints that imply the game was originally going to have rainfall, as it's raining in the intro, whenever Batman is inside the medical facility, and guards and prisoners are wearing raincoats, despite the clear weather everywhere else. The remaster adds rainfall in free roam.

* In the ''VideoGame/MetalGearSolid2'' graphic novel and motion comic adaptation, Snake's holdup of Olga is massively compressed, so she takes her gun, throws it overboard, and it's followed immediately by a gun battle. How she has a gun after throwing it away isn't explained. (In the original game, she had a second gun disguised as a knife and a USP strapped to her back, which Snake was in the process of relieving her of before she managed to [[DistractedByTheSexy distract him]].)

* ''VideoGame/TheBourneConspiracy'' video game follows the plot of the first Bourne movie pretty accurately except for some added [[AdaptationExpansion flashback missions]] and a runup to the hit on Wombosi at the start. However this actually hurts the premise since it makes the Treadstone program look not so bad, and Bourne more like a coward than someone with principles. The game doesn't allow you to use lethal force against civilians or police, something the movie implied that Treadstone was quite lax about, it creates an odd moral issue when Bourne gets a burst of conscience and can't kill Wombosi, despite that he [[WhatMeasureIsAMook slaughtered dozens of his mooks]] to get to him and also killed Wombosi's [[TheDragon Dragon]], (a character that doesn't appear in the film), and depicts the flashback missions as quite noble and just despite the film implying that they often consisted of killing innocent people who happened to inconvenience the [[CIAEvilFBIGood CIA]], involving things like fighting off a terrorist assault on an airport and stopping a terrorist from obtaining a dirty bomb. Pre-amnesia Bourne and Conklin come across more like ruthless Anti-Heroes rather than the immoral killers as portrayed in the movie.
