Character Rerailment is what happens when a [[CharacterDerailment derailed character]] returns to their previous characterization. Generally this signals the end of a DorkAge. This may also follow a [[RunningTheAsylum changing of the guard at the asylum]]. May also happen repeatedly if a character bounces [[DependingOnTheWriter between writers]]. Sometimes the time spent derailed turns out to be AllJustADream.

Sometimes used as an AuthorsSavingThrow. A temporary reversion to prior characterization is a CharacterCheck. See also, WeWantOurJerkBack, FlowersForAlgernonSyndrome.



[[folder:Anime & Manga]]
* While in the past two or three volumes, she was [[AxCrazy murderously insane]] in every single chapter, in volume 8 of ''Manga/SayonaraZetsubouSensei'', Chiri returns to her original characterization as [[SuperOCD very uptight]], but still somewhat the StraightMan.
* Orihime Inoue from ''Manga/{{Bleach}}'' is an odd case of rerailment due to CharacterDevelopment instead of undoing CharacterDerailment. She has recently gone back to being her humorous, perky self like how she was to begin with rather than the [[BrokenBird broken, emotional character]] she's been portrayed as throughout the Hueco Mundo arc as a result of a MASSIVE BreakTheCutie process that involved her being kidnapped, being mentally/physically/sexually (manga only) harrassed by the enemy, being forced to see her friends being hurt in several ways, and ultimately watching her LoveInterest being beaten to near death. This is because all her issues from said arc were wrapped up and she was free to be a content person once more, [[PluckyGirl with added life experiences and stronger determination]].
* Mamoru Chiba/Darian from ''Anime/SailorMoon'' was subjected to quite the CharacterDerailment in the R season, going from a polite young man who still [[BrutalHonesty didn't unnecessarily sugarcoat his words]] and ''did'' tell his (much-younger) girlfriend and her friends what he had in his mind, to a {{Angst}}y and broken mess who acted borderline abusive to her, badmouthing her to keep her away and safe, and caused her lots of turmoil (which once almost ''killed her'' since he would not tell her what he ''did'' have his reasons... when in fact said reasons ''did'' involve her and she had all the right to know). Fortunately, once he finally told her the truth and the arc reached its end, Mamoru's OutOfCharacter half-season was put in a shelf and he returned to be the Senshi's BigBrotherMentor and a kind yet sincere boyfriend to Usagi. [[NeverLiveItDown Too bad fandom won't let him live it down, though]].... him being put heavily OutOfFocus in the next few seasons didn't help matters either.
* The [[LongRunnerCastTurnover few constants]] among the ''Anime/{{Pokemon}}'' cast seem to be re-hitting their stride in [[VideoGame/PokemonXAndY the XY saga]].
** [[TerribleTrio Jessie, James, and Meowth]] were first introduced as true members of the evil Team Rocket organization, constantly obeying their leader [[BigBad Giovanni]] all the time. But after their obsession with capturing Ash Ketchum's Pikachu began in the show's second episode, they started to ignore Giovanni and mainly went after Pikachu, which inevitably resulted in them constantly getting kicked around and "being blasted off again" every single time, even when Ash continued his journeys beyond Kanto. By Sinnoh, they had gone from their original intentions of {{Ineffectual Sympathetic Villain}}s to an outright GoldfishPoopGang with silly dances and Boss Fantasies being seen as outright detrimental to both the show in general and the Terrible [=TRio=] specifically. The writers for the ''Best Wishes'' arc made them super competent and super important; which generated (yet another) BrokenBase and was ultimately seen as [[CerebusSyndrome swinging the pendulum too far the other way]]. Early Kalos seems to have split the difference, wherein Team Rocket's plans are self-contained and usually doomed to failure, yet Pikachu is now an ''occasional'' target, giving way to the [[VictimOfTheWeek Pokémon of the Week]] [[note]]which sometimes is not a Pokémon[[/note]] and the trio sometimes still putting up a NotSoHarmless offence against Ash's team that led to intense two-way fights instead of one-sided beatings. This has struck fans early on as a "happy medium." Unfortunately, they became more overexposed and less useful to the plot as the series went on, with VillainDecay once again seeping in, [[UnpleasableFanbase leading to fan dissatisfaction once again]].
** Ash ''[[IdiotHero himself]]'' seems to be undergoing this in Kalos as well. In Hoenn, he served as a BigBrotherMentor to Max and an equal to May. In Sinnoh, his {{Idiot|Hero}} traits are more pronounced, but he still comes off as somewhat capable, at least when he's not up against a CreatorsPet or a DiabolusExMachina. In Unova, he was [[IdiotBall completely rebooted into a full-fledged rookie]], [[StrongAsTheyNeedToBe except when the plot required otherwise]], taking a backseat to his own sidekicks Iris and Cilan half the time. In Kalos, however, he returns to Hoenn-era form; he's still a bit wide-eyed, but most of his faux pas early on have come from lack of knowledge of the new region's dynamics, as opposed to the outright virtual lobotomy in Unova. It helps that [[EstablishingCharacterMoment he started Kalos with a]] [[Awesome/{{Pokemon}} Moment of Awesome]] [[note]]climbing the Poké-equivalent of the Eiffel Tower to peacefully subdue a rampaging Garchomp[[/note]], is a quasi-BigBrotherMentor to Bonnie [[note]]her ''actual'' big brother Clemont notwithstanding[[/note]], and also has Serena to play off as she's [[TheWatson the novice of the group]].
*** Kalos had it's own lingering flaws by the end of it's run in terms of Ash's [[VanillaProtagonist somewhat vanilla and overly serious personality]], being a capable battler but lacking much else in terms of quirks besides being very upbeat and forever engrossed by Pokemon. Alola fills in this remaining hole, making Ash still competent and insightful, but much more emotive and childlike again, and even reemerging some of his {{Adorkable}} or {{Butt Monkey}} qualities without undermining his gained experience as a trainer too heavily, and sometimes even blending it into making him CrazyAwesome in strategy and training.
* ''Franchise/DragonBall''
** Goku is an example of how this trope can backfire. Creator/AkiraToriyama expressed displeasure with the gradual AdaptationalHeroism Goku went through in the anime version of the story, [[WordOfGod saying that]] the character was always supposed to be a fight-obsessed simpleton who has a poor grasp of standard social mores and family values. ''Anime/DragonBallSuper'', with Toriyama at the helm, puts Goku back in line with the original ideal, even having a scene where Goku himself says that he's not a hero, just a guy who loves a good fight more than anything else[[note]]he does acknowledge his fighting villains like Freeza, but simply says that he's not going to ignore a person in trouble[[/note]]. However, this has caused a bit of backlash among the fandom since without the adapted heroism, Goku does insane things just to get a good fight, such as putting a hit out on himself because he wanted to fight the assassin on equal terms or even worse, be fully willing to let at least 7 universes erased just for the sake of having a good fight. To fans who weren't aware of Toriyama's intentions it can look like Goku has taken a firm hold of the IdiotBall or JerkassBall, and even those who do know aren't happy.
** Frieza, on the other hand, is an example of how this trope can play out positively. After his time as the ArcVillain and BigBad was up, the manga had Frieza [[AntiClimax anticlamactically]] [[TheWorfEffect worfed]] by future Trunks, whereafter he quit appearing, leaving him a memorable villain who simply got outstripped after his time in the limelight had ended, but nothing uncommonly undignified. The [[{{Filler}} anime]] and other extended media, however, kept bringing him back after this point and had him unceremonously subjected to [[VillainDecay more one-sided beatdowns]], and started characterizing him as a SmallNameBigEgo in the bigger scheme of things who CantCatchUp to the heroes. During ''Anime/ResurrectionF'', however, not only are all of his previous defeats explicitly removed from continuity, it is revealed that Frieza is an insanely talented prodigy who simply had never trained. During his comeback, Frieza returns as an opponent with power and cruelty to be feared, and his [[spoiler: second return during the Universe Survival Arc drives the point home that, regardless of whatever more powerful or skilled opponents Goku may face, Frieza will always be his most hated and vicious foe.]]

[[folder:Comic Books]]
* ''ComicBook/BuffyTheVampireSlayer: Season 8'' rerails several members of the cast after their derailment in Seasons 6 and 7, while at the same time continuing their character development. Some, however, still haven't really recovered (Giles, Amy, Buffy herself to a widly varying degree, etc.)
** With Giles, they at least took his character derailment to its logical conclusion of [[spoiler: RedemptionEqualsDeath]].
* A number of comic book characters have gone through this. Like Franchise/{{Batman}}, who swings between {{Jerkass}} behavior and being called out on it, typically going on a trip to rediscover himself.
** ComicBook/{{Nightwing}} underwent a similar process after Devin Grayson's disastrous run on the series, which had him join Deathstroke as Renegade. The ResetButton on that one was pounded so hard it ''cracked''.
** For Nightwing, it was a case of rerailment or death. Creator/DanDiDio has stated that it was originally planned to have Nightwing die at the end of ComicBook/InfiniteCrisis (if you've read it, you can probably figure out where), and he kind of implies that Devin Grayson's handling of the character is one of the reasons.
** This seems to be a pattern with Batman characters, including the case of Cassandra Cain, the second Batgirl... for a while, at least. After she was revealed to [[FaceHeelTurn have thrown out her heroic side and become evil]], later writers retconned this by saying that she was under the control of Deathstroke through a drug, only to have her swing ''back'' to killing people again. Poor girl can't catch a break. Later, she would go back to not killing, with the second turn to killing ignored.
** ComicBook/TheJoker is a particularly poignant example; initially a murderous criminal who just ''happened'' to [[{{Idiosyncrazy}} look like a clown and sometimes use modified joke paraphenalia]] in his crimes, the [[UsefulNotes/TheGoldenAgeOfComicBooks Golden Age]] Joker went from a cold, grim and relatively rational but bad-tempered professional criminal to a harmless and super-wacky "robbing jester" during [[UsefulNotes/TheSilverAgeOfComicBooks the Silver Age stories]]. Finally, the Bronze Age brought the two takes of the character together for the first time in "The Joker's Five-Way Revenge", establishing the wacky-but-horrifically-evil personality that has become his defining characterization ever since. However, the pendulum swung too far in the ''other'' direction, with The Joker doing things like ''cutting off his own face'' and wearing it. ''ComicBook/DCRebirth'' is in process of rerailing by explaining there are ''three'' Jokers.
** ComicBook/{{Bane}} has had this a lot. He started out as a GeniusBruiser that used a drug called Venom to augment his already impressive strength, and managed to exhaust Batman enough that he easily won their first fight, and broke Batman's back. He basically became known for ''only'' breaking Batman's back and his use of venom, and became DumbMuscle subject to TheWorfEffect. Gail Simone's ''ComicBook/SecretSix'' run would revert him to GeniusBruiser and have him try to wean himself off Venom. ''However'', then the New 52 reboot hit and Bane was back to being DumbMuscle and constantly using Venom, though ''sometimes'' showed a GeniusBruiser side. Eventually, Tom King would revert him to GeniusBruiser in his ''Batman'' run, while having Bane's Venom use be a more mental thing, with it not only augmenting his considerable physical strength, but also removing his ability to feel fear, implied to be why Bane ''really'' used Venom.
* Franchise/GreenLantern Hal Jordan went through this after he [[FaceHeelTurn went insane]] and killed most of the other Lanterns. It was eventually revealed in ''Green Lantern: Rebirth'' that he'd been possessed by Parallax, the embodiment of fear, and he proceeded to regain his true heroic self; though at the time this seemed like an AssPull to some, both Parallax and the Sinestro Corps have gone on to become an integral part of the Green Lantern mythos. Oh, and several of the dead Lanterns turned out to be alive.
* Writer Creator/PeterDavid, who wrote ''ComicBook/IncredibleHulk'' for 12 years, disliked the changes made by a subsequent writer so much that when he came back to write the title, he had the entire previous storyline revealed to have been AllJustADream.
* At this point, there are at least three different characterizations of ComicBook/{{Magneto}}, with authors repeatedly [[ArmedWithCanon rerailing one by derailing the others]]. The original characterization was a generically evil BigBad. Creator/ChrisClaremont's tormented WellIntentionedExtremist is the most complex and long-running, considered his "true" self by most, but Creator/GrantMorrison's AxCrazy villain is closer to the character's roots. However, nobody complained about Magneto's return to the character he'd been from 1975 to 2003 immediately after by Claremont himself, with Morrison's Magneto revealed as an impostor. Morrison, however, wasn't the first to try and make him TheHeavy again, though they did make sure he had sufficient provocation for "Fatal Attractions" back in the 90s.
* Alan Davis dismissed a later writer's run on ''Comicbook/ClanDestine'' as a dream. It was hilarious because it was just a single-line throwaway.
* Comicbook/ThePunisher famously went through a 90s DorkAge where he was reimagined as a supernatural character who hunted demons at the behest of Angels from Heaven. Creator/GarthEnnis took over the character and brought him back to his gritty roots, with the Heaven stuff dismissed with a single (now iconic) HandWave line:
-->'''Punisher''': Tried it. Didn't like it.
* Creator/{{Christopher Priest|Comics}} used the same tactic when he got ahold of Comicbook/TheCreeper during his ''Comicbook/{{Deathstroke}}'' run. The Creeper had previously been heavily reimagined in the ComicBook/New52 as a DarkerAndEdgier Japanese {{Oni}}, much to the ire of his fans. Priest brought back the character's original appearance, and only mentioned the Oni stuff in passing with a line saying that the Creeper had been going through some changes recently, but was now feeling like his old self again.
* ComicBook/{{Gambit}} started off as a RuleOfCool-based, MrFanservice ManipulativeBastard HandsomeLech [[DeathDealer Death Dealing]] BadassLongcoat who relished the challenge of getting his hands on the ForbiddenFruit Rogue, though stymied by his self-centered JerkAss qualities and the large number of people he pissed off in his thief career. Then, Rogue left him to die in Antarctica. After this, the result was a lot of {{Angst}} on Gambit's part, whose characterization was changed from the previously-described version to a [[{{Angst}} Self-loathing]] [[TheAtoner Atoner]] desperate to punish himself for his (morally blameless) role in the Mutant Massacre. More recent adaptations, however, have reached back to the character's roots: ''Film/XMenOriginsWolverine'' showed Gambit as competent, charming, handsome and relatively low-angst [[TheGambler card-shark]] who won a CoolPlane in a poker game, and ''WesternAnimation/WolverineAndTheXMen'' had Gambit as a mercenary, ruthless, charming, manipulative thief for hire (albeit in only two episodes). Whether or not this trend will continue is currently unknown, though his recent solo series, which compromises by having him return to his thieving roots and ultimately becoming King of Thieves, while remaining a loose faculty member at the Jean Grey School (Wolverine explains that they don't actually expect him to turn up much... but they trust him to be there when it counts, when he's really needed), before joining X-Factor, but still remaining King of Thieves.
** However, his role in the Mutant Massacre brings him to derailment in other ways: he's a villain in both ''WesternAnimation/XMenEvolution'' and ''WATXM,'' because apparently leading the Marauders to the Morlock tunnels having ''no idea'' what's about to happen makes you a bad guy. However, it's softer in X-Evo, as he's found in the employ of Magneto, whose CharacterDevelopment is well on its way (though he's still mostly in opposition to the X-Men) by the time Gambit shows up. Still, we last saw Gambit as an X-Man in animation in the 1990s series.
* The entire purpose of ''ComicBook/OneMoreDay'' was to get Franchise/SpiderMan single again and make him "young and fresh" again. In order to do this, he was made to [[CharacterDerailment make a deal with Mephisto to save his aunt from dying, at the cost of his wife and unborn child]], then was reset to being single, "young and fresh", and... living with his elderly aunt again. Safe to say, this [[ThisLoserIsYou didn't work out so well]], but later writers have done their best to salvage it.
* Shatterstar's an odd case in that the "rerailment" wasn't to his original characterization. ''ComicBook/XForce'' had him slowly lose his rage, but handled it believably, and didn't give him BadassDecay. Rob Liefeld's work on the series snapped him back to his old self, but didn't do much with the possibilities involved. ''ComicBook/XFactor'' toned him down again, and has had more of a positive reception.
* Speedball's infamous transition from wacky comic relief to self-hating [[TheAtoner atoner]] in ''ComicBook/CivilWar'' has been undone, redone, and partially undone again as different writers debate over the character. As of ''Heroic Age'', he's still haunted by his memories, but he's slowly recovering.
* In ''ComicBook/TheTransformersAllHailMegatron'', Prowl, the normally level-headed second in command, reveals a darker side, and shows him as a schemer doing what may be unethical but necessary to win the war (here having the mind of a respected soldier altered to serve his purposes). In ''ComicBook/TheTransformersIDW'' his personality does a 180 and he becomes a self-sacrificial maverick, tries to save a Decepticon, and acts like the kind of rule-breaker he previously hated, this carries over to Infestation, but not to the concurrent ''ComicBook/TheTransformersLastStandOfTheWreckers'' wherein he manipulated many events behind the story. ''ComicBook/TheTransformersRobotsInDisguise'' has Prowl revert to his scheming, being more irrational and hot-headed, but still bending the rules for what he feels is the greater good. He remarks that his actions in the previous series were irrational and brought on by too much trust. He's caught in an ArmedWithCanon tug-of-war and prone to repeatedly deciding that he was wrong during the previous writer's take on him and should have stayed like the writer before that had him.
* An issue of Chris Claremont's ''Franchise/XMen'' had the villain Arcade light a match on Comicbook/DoctorDoom's armour, with Doom just allowing it. Many felt this was CharacterDerailment, and as it turns out, so did John Byrne. During his run on the title, he retconned that the Doom who worked with Arcade was actually a Doombot, and when the real Doom questions it on how he killed Arcade for such an act, the Doombot says it did not, for it felt Doom may need Arcade. [[https://c1.staticflickr.com/9/8100/8559598933_ed6cfbbdb0_b.jpg Doom then casually destroys the Doombot]], exclaiming, "Doom needs ''no one''." This actually became one of Doom's most memorable moments as a character.
* Comicbook/{{Supergirl}} was originally a short-tempered but optimistic, sweet girl. When she was reintroduced in 2004, editors thought the best way to bring the character up to date was characterizing her as a permanently angry, immature, edgy jerkass. Fans hated it and mass-dropped the book. The next creative team hurried to revert her to her kind-hearted self, and writer Sterling Gates dismissed her initial weird characterization as temporary Kryptonite-induced craziness. No one complained.
* ComicBook/{{Carnage}} became increasingly megalomaniacal in the 2011 ''Carnage USA'' and 2014 ''Minimum Carnage'' story arcs, taking over the town of Doverton, Colorado in the former and seeking to conquer the Microverse in the latter. In ''Superior Carnage Annual'', however, Cletus remarks that he doesn't know what came over him and decides to go back to his roots as a chaos-obsessed mass-murderer.
--> '''Cletus:''' Dreaming of [[TakeOverTheCity taking over cities]]... [[DimensionLord conquering tiny universes]]. Thought I was thinking big! But those kinds of ambitions... they're ''lies''. Now the cataracts have been peeled from my eyes! I can see clearly! Back to the basics! Simple... beautiful... ''random'' ...Carnage!

[[folder:Fan Fiction]]
* FanFic [[{{MST}} Sporkings]] sometimes have the characters derailed in the fic comment on what the character would have actually done in whatever situation the fic describes.

* Before ''Series/TheAdventuresOfSherlockHolmes'' (see below), the Literature/SherlockHolmes meets UsefulNotes/JackTheRipper film ''Film/MurderByDecree'' made a good-faith effort to rescue Watson from his post-Nigel Bruce image as a dundering blockhead. James Mason's Watson is an occasional DeadpanSnarker who makes one of the biggest contributions to solving the case, when he isn't taking out a much younger man in a fistfight.
* ''Film/CurseOfChucky'' brings the titular killer doll back to his original characterization, and out of his {{flanderiz|ation}}ed StupidEvil traits.
* With Stephen Hillenburg back at the helm of ''WesternAnimation/TheSpongeBobMovieSpongeOutOfWater'', the characters in the ''WesternAnimation/SpongeBobSquarePants'' franchise are closer in characterization to the first three seasons than when he stepped down.
** After suffering from [[TookALevelInJerkass being an uncaring, money-worshipping sociopath]] for several seasons on the show, Mr. Krabs seems to be more like the JerkWithAHeartOfGold that he was in the first seasons, with the money-loving aspect toned down to what it was before {{Flanderization}} set in. He's still kind of a jerk, though nowhere near as bad as he is in his worst episodes.
** [=SpongeBob=] himself especially seems to have been hit with this. Still an AmbiguouslyGay {{Cloudcuckoolander}}, but here he is ''much'' less obnoxious than his Flanderized season 5+ self, and appears to be less of an IdiotHero. Not to mention that [[VocalEvolution his voice is lower - like in the old episodes.]]
** Similar to Mr. Krabs, it appears Patrick is now be back to his [[TheDitz old goofy self]], as opposed to the [[TookALevelInDumbass brain-dead]] [[TookALevelInJerkass sociopath]] he was from seasons 5-8. [[TookALevelinJerkass He's still part of the angry mob after Spongebob]], but he gets better.
** After three seasons of being comically inept as a villain to the point he needed his computer wife to ''tell him to blink'', Plankton is back in this movie as a serious threat who actually comes really close to stealing the formula.
** Squidward's ButtMonkey status is heavily minimized, and he even gets [[ThrowTheDogABone thrown a bone]].
* In ''Film/TeenageMutantNinjaTurtles2014'', Vernon's portrayal which sees him as friends with April who helps her and Raph rescue the others has him closer to how he originally was portrayed in the first season of [[WesternAnimation/TeenageMutantNinjaTurtles1987 the '87 cartoon]] before he TookALevelInJerkass and became April's cowardly rival.
* It's argued that ''Film/TheDarkKnight'''s Joker is a rerailment of the character as he appeared way back in the Golden Age: he doesn't bother with giant jack-in-the-boxes or acid-squirting corsages, used public announcements to terrify Gotham, and despite ''having'' an evil laugh, he was far from a giggling loon (in fact, his expression was usually pretty dead).
* ''Film/RogueOne'' and ''Film/TheLastJedi'' take two of the original trilogy's most beloved characters back to their roots in magnificent fashion: In ''Rogue One'', [[spoiler: Darth Vader is shown as an unstoppable, terrifying, borderline-horror film-level '''[[TheDreaded MONSTER]]''' who wades through rebels like he's carving a cake,]] and ''The Last Jedi'' undoes many years of {{Flanderization}} by returning [[spoiler: Yoda to the goofy, expressive, optimistic TricksterMentor he was in the first films, and keeps his famous speech pattern to an appropriate minimum. Plus, he's also portrayed by an actual ''puppet'' rather than CGI.]]
* ''Film/JusticeLeague2017'': [[spoiler:After being a ClassicalAntiHero with emotional hang-ups in the [[Film/ManOfSteel first]] [[Film/BatmanVSupermanDawnOfJustice two]] movies, Superman is portrayed with his [[TheCape more]] [[TheParagon traditional]] [[IdealHero characterization]]. Even his costume has its color back.]]

[[folder:Live Action TV]]
* ''Series/DoctorWho'':
** The Doctor himself:
*** The Third Doctor era had done a drastic ReTool into a SpyFiction-influenced series, with the Third Doctor being a radical departure from the first two Doctors in that his TARDIS was broken and, stranded on Earth, he'd taken a job with the military. While this era is well-liked, some regard the characterisation as ''Doctor Who'' InNameOnly, between the Doctor tending to throw his social class around a lot more and the fact that the setup seemed to play down the appealing points of the character. When he regenerated into the Fourth Doctor he reverted to a clownish characterisation quite similar to the Second Doctor (although this developed in a more [[CreepyGood nuanced]] and [[HiddenDepths rounded]] direction after his first serial) and cut most of his ties to Earth and UNIT, in favour of the wild space travel and battles with monsters upon which the first two had focused.
*** The Seventh Doctor era attempted - at first - to make the Doctor a lot LighterAndSofter, making him a foolish CloudCuckooLander who didn't seem to have a clue what was going on and would break into vaudeville spoon-playing and clowning. In addition to this being a very shallow interpretation of the Doctor's characterisation, it caused severe whiplash coming as it did after an era with a particularly {{Jerkass}} Doctor who had featured in some very dark and violent stories. However, once the ExecutiveMeddling eased up, the script editor and Creator/SylvesterMcCoy teamed up to gradually rerail the Doctor back into being a mysterious, powerful and frightening figure, who just also happened to be a loveable figure of fun into the bargain as well, as he had always been before that and will likely always be after.
** The Cybermen from ''Series/DoctorWho'' were originally an emotionless and monotone species of cyborgs. From ''[[Recap/DoctorWhoS19E6Earthshock Earthshock]]'' onwards they turned into generic gun carrying evildoers. This was finally fixed in the New Series and AudioPlay/BigFinishDoctorWho audio stories.
* ''Series/TheAdventuresOfSherlockHolmes'' (and its successors) went to great pains to avoid the image of [[TheWatson Watson]] as a fat, blundering old moron who couldn't see that the sun had risen until Holmes point it out to him, and turned him back into the young, fit, and incredibly accomplished surgeon with military background who, while still nowhere near as bright as Holmes, was still very intelligent in his own right.
** On a related note, ''Series/{{Sherlock}}'' accomplished this on more than one level. Not only is it one of the few screen adaptations to refrain from severely downplaying the title character's [[NoSocialSkills limited people skills]], but the SettingUpdate allowed the producers to carry out a ''Genre'' Rerailment from UnintentionalPeriodPiece to crime fiction.
* Television did this for both ''Franchise/PerryMason'' and ''Series/ElleryQueen''. In different series of movies in the 30s and 40s, Mason was depicted as a hard-living playboy with lavish offices and expensive tastes, while Queen was a comic bungler who was TooDumbToLive. It took Raymond Burr (Mason) and Jim Hutton (Queen) to bring those characters back to the authors' original characterizations (which were far more serious and sensible).
* In ''Series/{{Charmed}}'' Phoebe's character was seriously derailed in Season 5 and remained loathed by the fanbase. But when Season 8 came along, we saw a return to a maturer version of the original Phoebe. She was a lot less self-centred and less boy crazy - her SerialRomeo lifestyle was actually Deconstructed.
* After a bout of serious {{Flanderization}} and CharacterDerailment in the previous seasons, the characters in ''Series/{{Community}}'' are returned to their original personalities in the fifth season, particularly Chang and Dean Pelton, who had become obnoxious cartoon characters by the fourth season.
* The last season of ''Series/TrueBlood'' rerailed Bill Comptom. In the first two seasons he was brooding guy with a few secrets [[spoiler: like being a spy]] but was trying to make up for his vampire nature by being nice and helpful to people and only drinking synthetic blood. Then in season three through six he became increasingly manipulative and callous and eventually megalomaniac. In the last season Bill saw the error of his ways and started trying to get rid other evil vampires and started being nice to the main cast again, especially main character Sookie who he finally started conversing with regularly again.
* ''Series/GameOfThrones'': Jaime's current storyline in the books ends with him being fed up with Cersei's madness and abandoning her, as snow begins to fall in his area, indicating that winter has finally come. Season 6 finale teased it with a DeathGlare he gave Cersei in the end after she blew up the Sept of Baelor with wildfire, but then he spend all Season 7 firmly at her side. Then in the Season 7 finale, he finally does the same decision as in the books, just as the snow begins to fall.

[[folder: Tabletop Games]]
* In ''TabletopGame/{{Warhammer 40000}}'' this seems to be happening slightly to [[BloodKnight Khorne]]. In recent fluff, he has been going back to his older self, his hounds are stated to be sent to hunt down any of his Champions who kill an innocent (or at least offer them to [[ProudWarriorRaceGuy Khorne]]). Not much, but hey. Progress.
** Those hounds also sent to hunt down those who run away from battle and abandon their fellow warriors.

[[folder:Video Games]]
* In ''VideoGame/DonkeyKongCountryReturns'', Cranky Kong is cranky again. (Yeah, how THAT CharacterDerailment ever managed to happen in the first place we'll never know...)
* ''Franchise/SonicTheHedgehog'':
** Earlier in the series, Knuckles went from a [[VideoGame/Sonic3AndKnuckles smug echidna who laughed at being able to outwit Sonic]] to a [[SonicAdventureSeries completely serious guardian who is a bit gullible]]. ''VideoGame/SonicHeroes'' attempted to combine the two portrayals into a bumbling [[TheLancer Lancer]] who is smug at getting one over Sonic. The game also marked the point in which Knuckles' HotBlooded nature and bumbling naivete started to get [[{{Flanderization}} exaggerated]] in a case of TookALevelInDumbass and BadassDecay. His role as guardian of Angel Island is also frequently neglected in favor of being another generic associate of Sonic. And then he returns to his ''Adventure'' persona again in ''VideoGame/SonicRunners''. They're still working on the "being a Guardian of the Master Emerald" thing. In the ''[[VideoGame/SonicBoom Sonic Boom]]'' [[WesternAnimation/SonicBoom continuity]], they addressed the derailment... by taking the bumbling nitwit characterization and running with it for the most humor, making him the DumbMuscle of the team. The Guardian aspect was dropped due to the Master Emerald not existing in the ''Boom'' continuity.
** Tails as well. For a few games, he simply became a walking toolkit for the team, losing the childlike and friendly aspects that made him interesting and likable in the first place (and that his character was built from). ''VideoGame/SonicColors'' undoes some of the damage, especially that done to his friendship with Sonic.
** Amy Rose. Originally an AllLovingHero with a [[DropTheHammer giant hammer]] [[{{Hammerspace}} that she kept pulling out of nowhere]], who had a crush on Sonic. She got a PlotRelevantAgeUp from eight to twelve come ''VideoGame/SonicAdventure'', in which she became an AllLovingHero and got much more persistent about her attraction to Sonic without being entirely unreasonable. Cue ''VideoGame/SonicHeroes'', where being a StalkerWithACrush had completely taken over her character. She derailed even further in ''VideoGame/SonicRiders'', becoming a SpoiledBrat, albeit one [[JerkassHasAPoint that had some good points about Sonic's actions at times]]. She was eventually rerailed in ''VideoGame/SonicUnleashed'', back to somewhere between ''[[VideoGame/SonicTheHedgehogCD Sonic CD]]'' and ''Sonic Adventure'' levels of crushing, though she'd have much less of a storyline role in the games onward. In the ''[[VideoGame/SonicBoom Sonic Boom]]'' [[WesternAnimation/SonicBoom continuity]], they addressed fan perceptions of the derailment by treating the ''Boom'' version as more of an ActionGirl, with elements of her AllLovingHero status returned. Her crush on Sonic is more nuanced and tolerable along the lines of ''CD'' and ''[=SA1=]-2'', along with her [[CannotSpitItOut trying to hide said crush]] instead of showing it.
** [[VideoGame/SonicAdventure2 Some]] [[VideoGame/SonicTheHedgehog2006 games]] tried to make [[BigBad Eggman]] a more serious villain and downplay his comedic attributes, only for the [[VideoGame/SonicHeroes next game]] to backpedal and revert him back to his comedy relief self. Starting from ''VideoGame/SonicUnleashed'' onward, he's kept the comic relief persona but the true dastardliness of his plans is hidden if you [[BewareTheSillyOnes only concentrate on]] ''[[BewareTheSillyOnes that]]'' [[BewareTheSillyOnes aspect]] of his character. Much like Sonic and Tails, ''VideoGame/SonicColors'' undid problems that he had in the modern era, such as [[EvilIsNotAToy falling victim to whatever forces he was using for world conquest]], and he was ultimately the final boss of the game.
** That being said, what counts as Character Derailment or Rerailment depends on the fan, due to the Sonic franchise's notoriously BrokenBase (and the series' constant admission onto the CerebusRollercoaster). Fans who started during the more serious periods, between ''VideoGame/SonicAdventure'' and ''VideoGame/SonicTheHedgehog2006'', consider the shift to the more humorous and less plot-intensive games from ''VideoGame/SonicUnleashed'' and onwards as Character Derailment and yearn for the serious, complicated stories of that middle era.
* Axel from ''VideoGame/KingdomHeartsChainOfMemories'' underwent massive characterization changes and BadassDecay in ''VideoGame/KingdomHeartsII''. ''VideoGame/KingdomHearts358DaysOver2'', set between the two games, attempts to explain how this happened; he had been friends and co-conspirators with Saïx, but gradually ended up bonding with Roxas and Xion instead, and using manipulative and underhanded means for what [[PoisonousFriend he at least claims is their own good]], leading Roxas to leave the Organization [[spoiler:and Xion to die fighting Roxas and be erased from everyone's memory]].
* In ''[[VideoGame/PrinceOfPersiaTheSandsOfTime The Sands of Time]]'', the Franchise/PrinceOfPersia was a snarky, slightly naive teenager ([[VagueAge possibly]]) fresh from his first battle. In the RatedMForMoney ''[[VideoGame/PrinceOfPersiaWarriorWithin Warrior Within]]'', he became dark, brooding, and occasionally yelled obscenities at his enemies. ''[[VideoGame/PrinceOfPersiaTheTwoThrones The Two Thrones]]'' backpedaled to the characterization from ''Sands'', but [[AuthorsSavingThrow justified]] his attitude in ''Warrior Within'' as the Prince's darker side -- who manifests in ''The Two Thrones'' as the Prince's SuperpoweredEvilSide.
* In ''VideoGame/BackyardSports: Sandlot Sluggers'', every character from the original games (except Pablo) went back to their original characterization (though not their look), winning huge applause in the process.
* ''Franchise/FinalFantasy'':
** ''VideoGame/CrisisCore'' did this for the ''VideoGame/FinalFantasyVII'' cast, particularly Cloud, Aerith and Yuffie. They weren't exactly the same as before, but this was {{justified|Trope}} by the game being set five years before the original game, and they were a lot closer to their original counterparts than they were in ''[[Anime/FinalFantasyVIIAdventChildren Advent Children]]'' and ''VideoGame/DirgeOfCerberus''. Aerith got her flirtiness and PluckyGirl traits back, Cloud regained his sense of humour and realistic levels of {{Angst}}, and Yuffie regained her snarkiness and manipulativeness.
** The original ''VideoGame/DissidiaFinalFantasy'' had portrayed Terra as a fearful, {{Wangst}}-ridden DamselScrappy who gets [[IHaveYouNowMyPretty tormented in a vaguely sexualised manner]] by the villains and saved a lot by various boys, a radical and [[{{Chickification}} borderline offensive]] departure from her original personality. This came under much criticism from fans in both the West and Japan. The expanded rerelease, ''Dissidia 012'', fixed as much as it could by rewriting her non-voiced dialogue to be braver and more optimistic, willing to do her best to fight but unhappy with the need to fight in the first place, but she's still wimpy in the cutscenes. The developers of ''[[VideoGame/DissidiaFinalFantasy2015 Dissidia (2015)]]'' stated that they redid Terra's voice and moves for their version because they wanted her to be "optimistic" this time.
** After his first trip down the angst mines for ''VideoGame/{{Kingdom Hearts|I}}'' in 2002 where he was given dialogue [[TheOtherMarty written for Vincent]], Cloud is gradually being readjusted to be closer to his original game personality in newer material. His bio in ''VideoGame/{{Theatrhythm|FinalFantasy}}'' describes him as an arrogant showoff, the trait that was originally the core of his character but had been [[DeadUnicornTrope since forgotten]]. ''VideoGame/DissidiaFinalFantasy2015'' had the developers hyping up that Cloud would have "a positive personality" in the game, with trailers showing him [[GrinOfAudacity smiling while fighting]], despite him having been a PerpetualFrowner ever since his original appearance. ''VideoGame/SuperSmashBros 4'' goes back to his classic power-set and gives him quotes and poses emphasising his InferioritySuperiorityComplex, and his design in ''VideoGame/FinalFantasyVIIRemake'' is more heavily based on his old design and less idealised.
** Even the aforementioned ''Dirge of Cerberus'' undid some of the damage for Cloud, showing that, with all of the emotional baggage he was still carrying from the original game ''finally'' out of the way along with the cure of his Geostigma (which further contributed to his feelings of guilt, depression, and isolation), Cloud was capable of dryly cracking a few jokes with his friends, even lightly ribbing on Vincent once or twice. (And he gets to [[{{Cloudcuckoolander}} talk to his motorbike like it's a person]].) ''VideoGame/KingdomHeartsII'' gave a brief glimpse of Cloud's original personality as well, as seen with the [[SnarkToSnarkCombat banter]] between him and [[VideoGame/FinalFantasyVIII Leon]] during TheWarSequence, though this was greatly overshadowed by Cloud's plot arc with Sephiroth and Tifa, which was essentially a retread of ''Advent Children'' with Tifa taking on Aerith's role.
** Cloud's plotline in ''VideoGame/MobiusFinalFantasy'' is there to serve as a (re)introduction to the character for fans who don't remember the original, and writes him extremely close to his original game characterisation. When his memory problems begin to make him doubt his own existence, he reacts with snark and determination rather than angst, at one point [[AsideGlance eyeing the camera]] to say "I got sick of moping." His arrogant streak is back, with his backhanded compliments to Wol and rudeness to Echo driving a lot of the storyline's humour. He's still aloof, but not so unreasonably that he isn't able to express open gratitude when Wol and Echo try to give him emotional support.
* ''VideoGame/WorldOfWarcraft'':
** Cataclysm'' turned Sylvanas back into her old bitchy, vengeful, bitter, snide, condescending, determined, manipulative self that had been gone since ''VideoGame/{{Warcraft}} III'', motivated now with self-preservation rather than revenge.
** ''Mists of Pandaria'' tried this with Tyrande. It didn't work and most people instead saw her as impulsive and stupid, failing basic military tactics and requiring someone several thousand years her junior to set her straight.
** ''Burning Crusade'' turned Illidan, a ''very'' complex character that threaded the line between AntiHero and AntiVillain, into a generic EvilOverlord just for the sake of giving the players a raid boss. Naturally fan outcry ensued, and many years later, in the ''Legion'' expansion, Illidan was brought BackFromTheDead and was restored to his previous personality of a morally ambiguous character [[WellIntentionedExtremist willing to do]] [[PayEvilUntoEvil anything]] to fight the Burning Legion.
* ''VideoGame/MortalKombat9'' does this to most of its cast. Johnny Cage is shown as being a [[JerkWithAHeartOfGold Hollywood douchebag with a heroic spirit]], instead of the ButtMonkey who serves no purpose aside from being killed off as a gag. Likewise, Jax goes from being a stereotypical {{Blaxploitation}} hero back to his role as the badass StraightMan of the cast. And [[BigBad Shao Kahn]] finally stops being a regular playable character, and returns to his spot as the overpowered FinalBoss.
* ''VideoGame/TalesOfMonkeyIsland'' rerailed most of the Monkey Island characters, especially [[spoiler:[=LeChuck=], who was truly evil and threatening again after his disappointing apparent subservience to Ozzie in ''VideoGame/EscapeFromMonkeyIsland''.]]
* This was one of the selling points of ''VisualNovel/PhoenixWrightAceAttorneyDualDestinies''. After the loss of his badge and his subsequent [[CharacterDerailment derailment]] into a ManipulativeBastard in ''VisualNovel/ApolloJusticeAceAttorney'', a lot of people wanted the old {{Adorkable}} NiceGuy Phoenix back. So in ''Dual Destinies'', he's back to being a lawyer again, and he's not half as much of a jerk -- though he's kept a few of the ''Apollo Justice''-era mannerisms, and he acts a little more like a TeamDad TricksterMentor, so his character in ''Dual Destinies'' is closer to a combination of this and CharacterDevelopment.
** Ema Skye's characterization from ''Apollo Justice: Ace Attorney'' also ruffled some feathers because she was no longer cheerful and enthusiastic but bored and disinterested because she hated her current job. She sat out a game (Bobby Fulbright taking her place in ''Dual Destinies'') but has returned to the cast in ''VisualNovel/PhoenixWrightAceAttorneySpiritOfJustice'', having successfully achieved her dream of becoming a forensic investigator and sporting a better outlook on life, more reminiscent of her teenage years.
* A perfect example of how this trope can lead to a BrokenBase is the case of the Brotherhood of Steel from ''Franchise/{{Fallout}}''. When introduced in [[VideoGame/{{Fallout 1}} the first game]], the Brotherhood were essentially a bunch of xenophobic jerks who claimed a vaguely noble origin/ideology of "protect the Wasteland from people abusing the technology of the past", but who were pretty clearly shown to be just douchebags who wanted to hog the best tech for themselves and use this to bully those around them. This is emphasized in [[VideoGame/{{Fallout 2}} the second game]], where they have lost their stranglehold on the supply of advanced technology and so are becoming increasingly irrelevant to the goings-on of the world around them. Then came ''VideoGame/{{Fallout 3}}'', where the Capital Wasteland Chapter of the Brotherhood had abandoned essentially all of the original Brotherhood's teachings and instead set themselves up as futuristic knights, striving to protect and defend the good people of the Capital Wasteland. Though it was called out InUniverse that this isn't the traditional ideology of the Brotherhood and the "Outcasts", Brotherhood members who left the Chapter rather than abandon their traditions, became an interactive minor faction in their own right, many older fans bitterly complained about the change, even as newer fans found them quite interesting. ''VideoGame/FalloutNewVegas'' attempted to rerail by showing how other Brotherhood Chapters elsewhere were still following their old traditions... slowly dying out in the process. Finally, in ''VideoGame/{{Fallout 4}}'', the Capital Wasteland Chapter of the Brotherhood of Steel re-emerged after having shaken off their former leader's philosophy and returning to their roots... which lead to fans of their depiction in the previous game complaining about the apparent CharacterDerailment.
* Samus Aran of the ''Franchise/{{Metroid}}'' series has historically been something of a HeroicMime, thanks to the lack of other characters to interact with. ''VideoGame/MetroidFusion'' gave her some private monologues, but the characterization matched the badass image she'd cultivated previously. A few games down the line, we got the highly-controversial ''VideoGame/MetroidOtherM'', which many fans viewed as nothing short of character assassination. Clumsy writing turned her relationship with former commanding officer and father figure Adam Malkovich into full-on abuse by stripping Samus of any agency she would've had if Adam weren't around. Then there was the infamous scene where Samus suffers a HeroicBSOD upon seeing Ridley, something which had never happened in the series before, even in games set before ''Other M''. Seven years later, Nintendo decided that ''VideoGame/MetroidIIReturnOfSamus'' deserved the ''VideoGame/MetroidZeroMission'' treatment, and ''VideoGame/MetroidSamusReturns'' was born. Once again, Samus is back to the stoic {{Determinator}} of old; if there was ever any doubt, [[spoiler:she even charges into the fight against Ridley at the very end of the game]].

* One of the darker arcs (Dark!Jareth arc) of the MegaCrossover FanWebcomic ''Webcomic/{{Roommates}}'' [[InvokedTrope invokes]] this in-universe mixed with a liberal dose of [[YouCantFightFate You Can't Fight Your Canon]]: After trying to be the hero (and failing) for 150 or so pages [[spoiler: Jareth]] snaps and reverts back to his original characterization and this SuperpoweredEvilSide of his tries to force the others back too. It's heartbreaking and asks the highly meta question: "Is it even possible for a fictional character to change or redeem himself? Or does the story define everything he can ever be?"

[[folder:Western Animation]]
* The {{Franchise/DCAU}} team has admitted that Superman got [[TheWorfEffect derailed into a punching bag]] during the first season of ''WesternAnimation/JusticeLeague'' and [[WorldOfCardboardSpeech took steps in later episodes to remind viewers]] why he's, well, ''{{Franchise/Superman}}''.
** ''WesternAnimation/BatmanBeyond'': After two seasons of CharacterDerailment into an unpleasable harpy, Dana Tan is finally restored to her original sweet and supportive characterization... in the {{Fully Absorbed|Finale}} DistantFinale.
* ''Franchise/Ben10'':
** One of the main points to the first season of ''WesternAnimation/Ben10UltimateAlien'' is to '''finally''' mend Kevin's abrupt, unexplained shift in characterization and powers that occurred in ''Alien Force'', ultimately culminating in [[spoiler: using his old, sanity-warping powers as a means to save the world, and becoming evil again as a side-effect.]]
** Mileages vary as to how well this worked out in the end though, as some feel that this effort to connect his original series characterization with his new one only succeeded in derailing ''both'' of them, with [[spoiler: his old one being retconned from truly sociopathic to a result of alien heritage, and his new one treated so seriously that his sudden change back to comic relief after the first season finale, with no more mention of what transpired before, was not taken well.]]
** Kevin's rerailment was tried ''again'' in ''Omniverse'', with [[TookALevelInJerkass even]] ''[[TookALevelInDumbass more]]'' [[ArtShift mixed]] results. It reached its most [[BrokenBase base-breaking]] level when it was {{Retcon}}ned that [[spoiler: almost EVERYTHING about Kevin's backstory and personality from the sequels was a mental fabrication by an evil faction of the Plumbers and that his HeelFaceTurn was all part of their master plan. Granted, Kevin redeems himself for real after learning this instead of follow through with his intended mission, but many fans of him from the previous sequel shows felt cheated all the same at having invested themselves in a total phony.]]
** The is zig-zagged with Ben himself in ''Omniverse''. His personality owes to the exaggerated moron from Season 3 of Alien Force, much to the irritation of the fans who liked him as a more competent and heroic character, but some episodes like "Malefactor" or "Max's Monster" do showcase him as smarter and more competent. Unfortunately, by the next episode he usually tends to get back to be a moron, and the writers hadn't settled on either portrayal by the series' end.
** Vilgax's characterization and vocals[[note]]Though rather than Creator/SteveBlum, he's voiced by Creator/JohnDimaggio.[[/note]] in one of the ''Alien Force'' video games, ''Vilgax Attacks!'', was much closer to how he was portrayed in the Original Series. He also regained his original series personality in the GrandFinale of ''WesternAnimation/Ben10UltimateAlien'', what with [[spoiler: [[DidYouJustScamCthulhu outsmarting a]] EldritchAbomination '''God''']] and what not.
** Zombozo, in the original series, was an undead, supernatural MonsterClown who was rather dangerous. ''Ultimate Alien'' seemed to remove the supernatural aspects in favor of a much more Joker-like character. ''Omniverse'' reworks the character to showcase him as more of a walking corpse who can stretch his arms, bringing the supernatural aspect of the character back. [[VillainDecay He's a little less effective]] and [[DenserAndWackier a little more comical]], though.
** Charmcaster had an accumulative derailment process in both ''Alien Force'' and ''Ultimate Alien'', with a totally new look and personality, and eventually practically crossing the MoralEventHorizon even though she'd never been that heinous a villain before and had in fact previously seemed to have a HeelFaceTurn. ''Omniverse'' restored her to her design from the original series, gave her a [[DenserAndWackier zanier version]] of her old immature personality, and an arc about going back to her old power-seeking ways as a means to heal from a mental breakdown: essentially a metaphor for her undergoing this trope. She's also left in a far better place for her to both mentally and morally improve at the end of the series, Gwen even [[LampshadeHanging lampshades the fact.]]
* ''WesternAnimation/TheSimpsons'':
** Homer goes from {{Jerkass}} to the original Homer sometimes at will.
** Ned Flanders, the namesake of {{Flanderization}}, returned to his earlier personality (a devout but accepting NiceGuy) in ''WesternAnimation/TheSimpsonsMovie''.
** Bart went through a failed attempt at this around 2010-12. He was initially BrattyHalfPint who frequently got in trouble for his outrageous pranks and snappy one-liners, but the coming of more "extreme" characters like [[WesternAnimation/SouthPark Eric Cartman]] and [[WesternAnimation/FamilyGuy Peter Griffin]], as well as [[ValuesDissonance society's more lax stance on child discipline]], made Bart's once-shocking antics seem tame by comparison. Episodes like "Love is a Many Strangled Thing" and "Postcard from the Wedge" tried to return him to his "bad boy" roots, but because of the writers' attempts to outdo his successors, Bart ended up coming off as [[TheSociopath a destructive, uncaring monster]].
* ''WesternAnimation/FamilyGuy'' subverted this trope with Stewie: in the season 9 premiere, he killed a character for the first time in years and revealed that he still wanted to kill Lois, although this still hasn't happened.
** Although Stewie attempted to make himself evil again after Brian called him out on how soft he had gotten. [[GoneHorriblyRight It worked]]. Unfortunately, the writers dialed this new evil Stewie's ChaoticEvil UpToEleven, turning him into a ChaoticStupid character, while completely discarding his mastermind-style LawfulEvil from the original characterization. [[IntendedAudienceReaction But then, that was the whole point.]]
** Joe was originally a HandicappedBadass cop who became an excuse to make cripple jokes after the show got UnCanceled. The previous characterization is somewhat more apparent in recent episodes such as "Joe's Revenge".
* ''WesternAnimation/SpongeBobSquarePants'': Many of the characters have undergone {{Flanderization}} after the movie. [=SpongeBob=] and Patrick TookALevelInDumbass, though the most notable change is Mr. Krabs' greed [[TookALevelInJerkass stooping to horrible levels]]. During Season 9, many of these changes were decreased and the characters began to act somewhat like their former selves, and even more in episodes aired after the second movie, which can be attributed to creator Stephen Hillenberg returning to the series.
* Most of the CharacterDerailment in ''WesternAnimation/TotalDrama Action'' was reverted in ''Total Drama World Tour''. Trent (although only a minor character) was back to being normal, Courtney stopped being evil and started being the [[SoapboxSadie holier-than-thou]] SmallNameBigEgo she was in season 1. Most of the characters who were {{flanderiz|ation}}ed like Owen and Bridgette returned to having multiple dimensions.
** In the SpinOff ''WesternAnimation/TotalDramaPresentsTheRidonculousRace'' Owen was rerailed further, becoming the AllLovingHero he was in ''Total Drama Island'' and losing any of the SmallNameBigEgo traits he hadn't quite lost in ''World Tour''.
* Recent characterizations of WesternAnimation/DaffyDuck have attempted, with varying levels of success, to get him back to his [[{{Cloudcuckoolander}} daffier]] roots.
* Although unintentional, the real reason why [[WesternAnimation/BeastWars Waspinator]] was portrayed as the ButtMonkey of the ''Franchise/{{Transformers}}'' franchise is because Hasbro actually found his cartoon voice extremely stupid. As a result he ended up getting kicked around and being blown up every single time, while muttering to himself "Waspinator has plansssss..." as he tries to put himself back together again. At the end of ''Beast Wars''' final episode, poor Waspinator is rescued by tribe of natives and crowned their leader, causing him to finally become "happy at last", but in ''WesternAnimation/BeastMachines'', he for some reason returned to Cybertron where he is immediately rehired by [[BigBad Megatron]], who then wipes his memory clean and transfers his spark into that of the Vehicon Thrust's (who is smarter, stronger, and more dangerous than Waspinator). When Waspinator-as-Thrust finally gets his memories back, he eventually starts to get kicked around and being blown up again, and when the Maximals [[spoiler: turn Cybertron into a second Earth]], they also transfer Waspinator's spark back into his original (but smaller) wasp mode again. In ''WesternAnimation/TransformersAnimated'' Waspinator returns, but is now known as Wasp instead, and he is changed into an extremely terrifying and powerful villain.
* Zigzagged with WesternAnimation/MickeyMouse: He was originally depicted as a brave action hero, but later shorts changed him into a laid-back slacker while WesternAnimation/DonaldDuck took the spotlight. Now, he's either back to being an action hero [[VideoGame/EpicMickey in several]] [[Franchise/KingdomHearts video games]], is [[WesternAnimation/HouseOfMouse the owner of a nightclub for other Disney characters]], or a ''WesternAnimation/DoraTheExplorer''-esque [[WesternAnimation/MickeyMouseClubhouse kids' show]] host.
* After suffering BadassDecay throughout most of ''WesternAnimation/UltimateSpiderMan'', Agent Phil Coulson reminds us that he is a [[BadassNormal SHIELD agent]] by fighting off a trio of Asgardians mounted on fire breathing wolves using a pair of {{BFG}}s that are almost as big as him.
--> '''Coulson''': No running in the halls.
** Not to mention holding his own against the Beetle (who in this version [[AdaptationalBadass has nearly Iron Man-grade]] PoweredArmor and previously was a difficult enemy for Spidey, Iron Fist, Power Man, Nova and White Tiger as a team) using nothing but a steel pipe he found lying around.
* Rufus and Amberley of ''WesternAnimation/TheDreamstone'' started off as {{Badass Normal}}s with distinctive personalities in the pilot, before quickly downgrading into [[TheGenericGuy generic]] incompetent {{Hero Antagonist}}s afterwards. Season 3 onward gradually reverts back to their original personalities and level of competence ([[TookALevelInBadass if not higher]]). Their UnscrupulousHero tendencies were also dialed back by the start of season 4, making them look more sympathetic and provoked against the Urpneys.
* Many of the engines' slowly waxed and waned in the long run of ''WesternAnimation/ThomasTheTankEngine'', some becoming almost polar opposites of their former selves. From Season 17 onward however, a new writing team was brought on board, reverting back many of the engines to their original personalities and refreshing its roots to ''Literature/TheRailwaySeries''. Some traits introduced in the TV show remain, albeit more as HiddenDepths.
* ''WesternAnimation/WabbitALooneyTunesProduction'':
** After being a whiny cynic on ''WesternAnimation/TheLooneyTunesShow'' Bugs Bunny is back to his {{KarmicTrickster}} personality he is better known for.
** Adding onto the above example, when Daffy Duck is reintroduced in the second season, his persona harks back completely to the initial ScrewySquirrel incarnation, perhaps more so than any appearance of him since the 1930s.
* Many fans disliked the Mayor of Townsville from ''WesternAnimation/ThePowerpuffGirls'' after he devolved into a moronic and insensitive manchild in the show's later seasons, but his older characterization of being a NiceGuy who is only slightly ditzy turns up in the 2014 special ''Dance Pantsed''. When Professor Utonium enters the DespairEventHorizon after Mojo Jojo controls the Powerpuff Girls' minds, the Mayor encourages the Professor not to give up on the girls. In addition, the Mayor feels remorse for insulting Ms. Bellum when she refused to open his jar of pickles and later apologizes to her for it.
* After all four of them suffered from CharacterDerailment in the previous season, the third season of ''WesterAnimation/TheLegendOfKorra'' rerails [[TheHero Korra]], [[GirlyBruiser Asami]], [[PluckyComicRelief Bolin]] and [[IronLady Lin Beifong]]. Within the first few episodes of that season, Korra's HotBlooded nature reaches a reasonable level again, after previously being amped up to a full blown HairTriggerTemper; Asami's [[ActionGirl back in action]], after inexplicably suffering {{Chickification}} and sitting on the sidelines for most of season two; Bolin's ditched his AcquiredSituationalNarcissism, and shed his [[IdiotHero downright moronic]] persona, returning to his previous characterization of [[NiceGuy well-meaning]] [[ManChild but somewhat immature]] supporter; and Lin is no longer relegated to [[DaChief playing the stereotypical police chief]] and [[IdiotBall inexplicably ignoring evidence for the sake of the plot]], instead getting a subplot of her own, multiple chances to show off her badassery and a showcase for her detective skills.
* This affects ''Literature/{{Franklin}}'' himself in ''Franklin and Friends'' at the start of an episode, right after one that contains a SnapBack or an AesopAmnesia that affected him.
* Onua's personality from ''Toys/{{Bionicle}}'' was very inconsistent despite him being a StaticCharacter. Originally a GeniusBruiser who only spoke if it was really necessary, the first movie (and the non-canon tie-in game) portrayed him more as a tough but jolly muscle guy. His [[Toys/{{Bionicle2015}} Generation 2]] counterpart was also meant to be wise and smart, to which the 2015 online webisodes didn't quite do justice, mostly due to how dumb the voice work made him sound. Finally, he got re-railed in ''The Journey to One'' animated mini-series: a soft-spoken and mature heavyweight, equally capable physically and mentally.
* ''WesternAnimation/HeyArnold'':
** In the last two seasons, Arnold, who was originally just a nice, normal kid was [[{{Flanderization}} flanderized]] into an omnibenevolent, advice giving savior who was never wrong and could do pretty much anything. He also became very [[FlatCharacter flat]] and OutOfFocus, to the point where the much more developed Helga almost [[SpotlightStealingSquad completely overshadowed him as the protagonist]]. Perhaps in response to this, "April Fool's Day" and "The Journal", the final two episodes (though the latter was a two-parter), returned the focus to Arnold and he more or less behaved like a normal kid would. But since this happened so late in the series, and the episodes aired OutOfOrder, it seems like a waste.
** Sid returns to his pre-Season 3 characterization (where he was much less of a {{Jerkass}}) in ''WesternAnimation/HeyArnoldTheJungleMovie'' and he spends the film being kind and courteous to his friends.
** To some degree, Harold and Stinky get some as well after [[TookALevelInJerkass taking some levels in the later seasons along with Sid]]. Stinky seems back to his confused but friendly southern demeanor and Harold doesn't bully anyone or boast about himself throughout the course of the movie. Harold is even seen beating a junky replica of Arnold when they are first imprisoned by Lasombra, only to be snuggling the same dummy later that night crying about how he misses Arnold.
* ''WesternAnimation/{{Archer}}'': In Season 5, Pam developed a cocaine addiction, and her ''whole character'' suddenly revolved around this. Not only this made her incredibly unfunny, but also turned her into TheMillstone. After noticing how much [[TheScrappy fans hated this]], in Season 6 her character was returned to her [[EnsembleDarkhorse much beloved]] persona from Seasons 3 and 4.
