** Sniffles was initially depicted as a generic nerd who was mainly defined by his rivalry with The Ant family. Later episodes played up his geeky personality and depicts him as the MadScientist who is gifted with the remarkable ability of building complex machinery.
** Flaky wasn't nearly as bashful in her first few appearances; in fact, she was mostly outgoing and only displayed rightful fear of genuine danger. For that matter, most Season one episodes ditch her worrisome demeanor almost entirely, to the point where she is willing to hang off a monkey bar in "Treasure Those Idol Moments" and had no problems hanging out with Flippy, a character she fears in later episodes.

** Thor’s character gets the massive overhaul from his first [[Film/{{Thor}} movie]] to his later appearances. In the 2011 film he’s a typical HotBlooded viking like the comics with the main levity of his character being the fact he’s a FishOutOfWater on Earth. By the time of ''Film/ThorRagnarok'', Thor has become more of a jokey GuileHero and in ''[[Film/AvengersInfinityWar Infinity War]]'', ''[[Film/AvengersEndgame Endgame]]'' and ''[[Film/ThorLoveAndThunder Love and Thunder]]'' is a freewheeling EmotionalBruiser who has a greater understanding of Earth customs (even sometime like ''VideoGame/{{Fortnite}}'') although he still has some of his original unawareness like calling Jane’s IV bag a “healing potion”.

** Sniffles was initially a generic nerd whose personality is best described as the ironically unsuccessful anteater fighting against a family of ants. Later episodes played up his geeky personality and depicts him as the MadScientist who is gifted with the remarkable ability to build complex machinery.

** Toothy, Giggles, and Petunia were much more childish and didn't have much traits differentiating each other. Toothy was mostly an impulsive beaver, Petunia didn't have much beyond interacting with Giggles, and Giggles herself was the [[TheSmurfettePrinciple token female alongside Petunia.]] In later episodes, Toothy is characterized as the most hardworking and [[ProneToTears sensitive one]], Petunia was ObsessivelyOrganized from the TV series and onwards, and Giggles has since been associated with romance and protecting the environment.
** Russell was much less social and acted like a true pirate, being all rough, always near the ocean, and even donning a [[PermaStubble five ol' clock shadow]]. He also exhibits less stupidity compared to the other critters and was one of the biggest butt-monkies in the series alongside Handy, Lifty, Shifty, and Toothy. Nowadays, he's one the most sociable characters, has a pirate motif and ocean-themed occupations at best, lives in a relatively suburban life otherwise, seems to lack common sense on a larger scale, and has a decent survival rate compared to his peers.
** Pop was originally written as one of the more callous and unlucky characters, in similar vein to Shifty, Lifty, Sniffles, Nutty, and Lumpy. The scrapped endings of two separate episodes had originally planned him to be somewhat cold, even to his own son's demise. A published episode even had Pop intentionally cause harm to Cub just to hide and fix his injuries. Pop's chance of dying was also more likely, with him being the only character who "rarely dies" to have his own Smoochie and die in his debut episode. In later episodes, he survives pretty often and doesn't act nearly as cruel (though, he can be a {{Jerkass}} on occasion).

* In the second ''Literature/LandOfOz'' book, ''Literature/TheMarvelousLandOfOz'', the Wizard of Oz is revealed to have conspired with Mombi to usurp the Ozian throne. He taught her all the magic she knows and gave her the infant Princess Ozma so that he could become ruler of Oz. In the fourth book ''Literature/DorothyAndTheWizardInOz'', suddenly he's a benevolent man who has never even ''met'' Ozma. This {{retcon}} was because children disliked the Wizard of Oz and thought he was a villain for all that he did. Creator/LFrankBaum tried to soften up his character.

* In his earliest appearances, Willkins is a fairly FlatCharacter, just being TheJeeves to someone who hates the idea of having servants. ''Literature/{{Jingo}}'' has him tone-shifting between his butler voice and a Sergeant-Major voice, which implies it's an affectation, and ''Literature/{{Thud}}'' reveals he grew up in the poorer parts of Ankh-Morpork, and was part of a particularly vicious street gang, with the humour coming from him describing this in the same precise manner one expects from a butler. By ''Literature/{{Snuff}}'', he's dropped this entirely, and while he's still deferential to Vimes and insists on the "proper" way of doing things, his style of speech is much more "one kid from the streets to another".

* Wrestling/TripleH: Hard to believe that [[ReasonableAuthorityFigure reasonable COO of the WWE]] started out as a WickedCultured {{Blueblood}}, became Wrestling/ShawnMichaels' AnythingThatMoves sidekick [[SidekickGraduationsStick and later]] leader of Wrestling/DGenerationX, to a SmugSnake {{Jerkass}} dragon to Wrestling/TheCorporation and the Corporate Ministry, then a MagnificentBastard before and during the [=McMahon-Helmsley=] Era, Determinator DesignatedHero after the quad injury, Bastard/Monster with [[ScrewTheRulesIHaveMoney with money]] in Wrestling/{{Evolution}}, FourthWallObserver after the DX reunion and finally, a BloodKnight vs. Wrestling/TheUndertaker at ''Wrestling/WrestleMania 27''. At heart, he was always a jerk, he just got A LOT more mic time as he rose to power.

* WebVideo/TheAngryVideoGameNerd was initially the Angry ''Nintendo'' Nerd, and only started calling himself by his much more well-known moniker after realizing there were quite a few other games and game systems he would receive requests to do reviews of. He also mostly stuck to games from the '80s, didn't have a theme song, and his first two videos were incredibly strange for two opposite reasons; the first video didn't show the Nerd at all and had him use an abelist slur to describe an aspect of the game, while the second was just him sitting at a computer and talking to the audience with only the odd screen shot. Also, The Nerd was much more thoroughly in-character during the earlier videos, and came off much less of a JerkWithAHeartOfGold compared to later and recent videos, refusing to use slurs to describe video games. Well, by comparison anyways...

* Franchise/{{Godzilla}}. In the appearance of the second Godzilla in ''Film/GodzillaRaidsAgain'', he acts just like his predecessor in ''Film/{{Go|dzilla1954}}jira'' where they were very destructive. Next comes ''Film/KingKongVsGodzilla'' where his personality changed to comical {{Jerkass}}, then acting like his old self, then laughing hysterically in ''Film/GhidorahTheThreeHeadedMonster''. If that's not enough, he became a superhero archetype in the 70's. Then it all ends with ''Film/DestroyAllMonsters''. No wonder Creator/IshiroHonda quit the series after ''Film/TerrorOfMechagodzilla''.

* Mineta in ''Fanfic/TheUndeadSchoolgirlDeadPulse'' starts as his canon ChivalrousPervert self. By the time of class starts at U.A., he's toned down his perversion by reading a sort of self-help book meant to help him keep from speaking his dirty thoughts all the time. Mineta's rather proud that he got through an entire conversation with [[GenderFlip Izuku]] without talking about her figure.
* ''Webcomic/FateGamersOnly'': Early comics have Rikku use her canon name "Gudako" and lack the UnlimitedWardrobe that becomes a recurring character trait.
* ''[[https://incorrectsmashbrosquotes.tumblr.com Incorrect Smash Bros Quotes]]'' had to invent [[VideoGame/SuperSmashBrosUltimate Galeem and Dharkon]]'s personalities wholesale due to them not ''having'' personalities in the game proper. As a result, said personalities were...rather inconsistent; Galeem leaned more cheerful and Dharkon more ominous, but overall the two were mostly interchangeable. Later quotes firmly established Galeem as the LightIsNotGood [[DeadpanSnarker snarky]] {{Jerkass}} and Dharkon as the DarkIsNotEvil [[TheDitz ditzy]] {{Keet}}, but it does make the two's earliest quotes a bit jarring.

*** In 2005, comic and book author Greg Farshtey got a free hand to write a novel about anything he wanted, and he made use of the opportunity to transform the character into a highly mastermind that [[IMeantToDoThat turned his former defeats to his advantage]] in his EvilPlan, and had a dry and sarcastic sense of humor, often coming off as a LargeHam. He was no longer "the" Makuta, much less an immaterial force, but rather a member of an entire species of Makuta with an elaborate backstory, a character, his own agenda and a new name: Teridax. His previous portrayals as a seemingly immaterial being were recontextualized by the revelation that his entire species had become EnergyBeings without real bodies underneath their armor.

* ''Webcomic/{{DetoxCamp}}'': Daisy's first appearance made her seem oddly bubbly and excitable, while later chapters show her much more subdued. The GeorgeLucasAlteredVersion of chapter 1 fixed this by toning down her initial excitement.

** Natasha Romanov aka Black Widow is quite different in her first appearance in ''Film/IronMan2'' compared the StoicWoobie and TeamMom seen in the later films. Firstly she was mainly just there to be an asskicking MsFanservice with only a little of her DeadpanSnarker traits seen in later films coming through during her bickering with Tony. It wasn’t until ''Film/{{The Avengers|2012}}'' that Nat became more of a character with a DarkAndTroubledPast who can outwit even Loki and her position as the emotional anchor for the team becoming more pronounced. Her [[Film/BlackWidow2021 solo movie]] showcases the fact she’s a BrokenBird at her core while still holding onto a lot her attributes (such as being a {{Guile Hero}}ine when dealing with egomaniacs) as well as her fanservice (at the insistence of the female director!).

** ''TabletopGame/ChangelingTheLost'': the True Fae in the first edition were depicted as AlwaysChaoticEvil bastards with BlueAndOrangeMorality who actively kidnapped humans on regular basis to turn them into Changelings for the sake of it. Their motivations were gradually fleshed out over the course of the various books, and the second edition eventually establishes the ones who go kidnapping humans are only a fraction of the whole; there are countless more who, while just as subject to BlueAndOrangeMorality as their kin, are content to stay in Arcadia, pursuing their own interests, rather than go mess with humans.

* ''Webanimation/RedVsBlue'': Caboose, presented as a socially inept new recruit gradually slips from an unintelligent human to a more alien-esque character who doesn't understand basic human norms and cannot follow a conversation. It is speculated that this is due to a shootout taking place inside his brain during the second season.

** One more from ''Moving Pictures'': It's the first appearance of Mrs Marietta Cosmpolite, and she's characterised by being "very broadminded", bordering on DirtyOldWoman; when she thinks Victor and Ginger are having sex, her reaction is a grin and "a complicated gesture he was sure little old ladies shouldn't know". This aspect of her personality is not reflected in The Way of Mrs Cosmpolite, as described in ''Witches Abroad'' and ''Thief of Time'', which portray her as a more ''conventional'' little old lady, and by ''Lu-Tze's Diary of Enlightenment'', one of the reasons she disapproves of Mrs Dolly Golightly (who the Way therefore sees as an Antichrist figure) is that she suspects her lodger isn't just her lodger, which is disgusting when her husband's barely been dead for ten years.

** In ''Guards! Guards!'' Sam Vimes has no strong opinions about Ankh-Morpork getting a king; he is cynical about the idea but more out of general cynicism, and it's Fred Colon who has the stronger anti-monarchist rant. In later books even the idea of monarchy is practically his BerserkButton.

** Toothy, Giggles, and Petunia were much more childish and didn't have much traits differentiating each other. Toothy was mostly an impulsive beaver, Petunia didn't have much beyond interacting with Giggles, and Giggles herself was the [[TheSmurfettePrinciple token female alongside Petunia.]] In later episodes, Toothy is characterized as the most hardworking and [[ProneToTears sensitive one]], Petunia was given SuperOCD from the TV series and onwards, and Giggles has since been associated with romance and protecting the environment.
