->'''Joel:''' We need some character development... in the... hizzy.\\

'''Joel:''' I do now! I'm a dynamic character!
-->-- '''WebAnimation/BonusStage'''

People change; it's a fact of life if not nature. However, change can be gradual, and people may keep the core of their character intact for much if not all of their life, just as a traumatic experience may well abruptly change someone completely. Characters reflect that. When a character finishes a story with a different outlook or personality from when they started, they are called a DynamicCharacter. It doesn't matter whether they had a [[RoundCharacter Deep and Nuanced personality]] or started life as a [[FlatCharacter cardboard cutout]], the character changes in either a subtle or overt way. We call this CharacterDevelopment.

Mind you, this isn't always the case, nor is its absence [[TropesAreNotBad bad]]. Contrast the StaticCharacter who begins and ends much the same as they began a story. Maybe they've learned something, but it doesn't change how they act.

The change a dynamic character experiences can be born of just about anything. It might 'evolve' them from a flat to a round character, but it might as easily simply change them into another kind of flat or rounded character. Then again, it could well ''flatten'' a rounded character if they suffer some kind of HeroicBSOD or related trauma.


[[folder:Anime and Manga]]
* Most of the characters in the ''Manga/FruitsBasket'' manga. The CharacterDevelopment in this series is staggering, and towards the end, nearly every character has undergone major growth. Best examples are Yuki, Kyo, and even Akito.
* Almost everybody from ''Manga/TeamMedicalDragon''. Character development and character depth is this manga's main strength and drive. Almost nobody stays the same as they are in the beginning of their appearance. Best example includes Noboru and Gunji.
* ''Manga/FullmetalAlchemist'': Edward Elric begins the series dependent on alchemy and doing everything himself. By the end of the series he has learned to depend more on his friends and share his burdens.
** [[Anime/FullmetalAlchemist The other version of Edward Elric]] also undergoes major changes over the course of his series, learning that there is a world outside of his own goals, and that he does not in fact have the answers to everything.
* One of the reasons Franchise/SailorMoon is cited as a [[GirlsNeedRoleModels good role model for girls]] is that she is [[ThisLoserIsYou like her target audience]] at first, having tendencies to be lazy, flaky, klutzy, and a crybaby, but then over five arcs becomes a MessianicArchetype and saves the galaxy.
* Haruka from ''Manga/KotouraSan'' went from CheerfulChild to BrokenBird, and back to an even more CheerfulChild in just [[TwelveEpisodeAnime twelve episodes]]. Her [[http://static.tvtropes.org/pmwiki/pub/images/k-s-haruka-comp-350-v2_7197.jpg profile picture]] in the series' character sheet makes a stark comparison between the first and last scenes of the anime.
* ''Manga/TokyoGhoul'' sees several members of the core cast evolve considerably over the course of the story, growing with their experiences and struggling to find balance in their personal conflicts or issues. The majority are very different from when they began the story, in particular the characters of [[MoralityAdjustment Kaneki]], [[TookALevelInKindness Juuzou]], [[LoveRedeems Nishiki]], and [[BecomingTheMask Tsukiyama]].
* Many ''Franchise/{{Gundam}}'' shows are noted for the CharacterDevelopment of its Protaganist, starting with Amuro in ''Anime/MobileSuitGundam''. He began the series as an anti-social and often self-centered teenager, but by the end of the series he became a dependable soldier, comrade, and AcePilot, not to mention his developing powerful [[PsychicPowers newtype powers]].
* ''Manga/YonaOfTheDawn'' does this with nearly everyone, the most apparent example being Yona herself. But even seemingly unimportant characters like [[TookALevelInKindness Tae-Jun]] get their time to shine.
* Ai Haibara aka Shiho Miyano from ''Manga/DetectiveConan'' starts off extremely terrified by the Black Organization and would often choose to commit suicide then face them. Thanks to the titular character and others' influence, she has decided to not run away from the organization, instead finding ways to bring them to justice.

[[folder:Films - Animation]]
* Gru from the ''WesternAnimation/DespicableMe'' franchise goes from a straight up {{jerkass}} with a few PetTheDog moments to someone with more open Heart of Gold moments with only a few jerky tendencies.
* ''WesternAnimation/TheBookOfLife'':
** Manolo learns to have the courage to be himself.
** Joaquin realizes the errors of his selfish attitude and drops it entirely by the end.
* Many characters from ''[[Franchise/DisneyAnimatedCanon Disney]]'' get this.
** [[Disney/BeautyAndTheBeast The Beast]] (thanks to Belle's influence) transforms from a haughty, ill-tempered SpoiledBrat to a mature, agreeable, and gentle being.
** [[Disney/{{Mulan}} Mulan]] becomes a more assertive and confident young woman.
** [[Disney/BigHero6 Hiro]] becomes wise, and mature, and inspirational -- a sharp contrast to the mischievous and lazy person he was in the beginning.
* Characters from [[Creator/DreamworksAnimation Dreamworks]] undergo character growth throughout their movie(s).
** [[WesternAnimation/ThePrinceOfEgypt Moses]] goes from an arrogant prince who holds an indifferent attitude towards the suffering Hebrews to the noble messenger of God who won't stop until his people are free from slavery.
** [[WesternAnimation/KungFuPanda The titular protagonist]], Po, gets a helping amount of growth in each of his movies.
** [[WesternAnimation/HowToTrainYourDragon Hiccup]] learns to accept all of his faults, while recognizing his strengths. Basically, he learns to [[BeYourself be himself]].

[[folder:Films - Live Action]]
* In ''Film/TheNextThreeDays'', John Brennan starts the movie as a community college lit. professor and a caring family man. But his wife is arrested and he decides to break her out of jail. In preparation for the attempt he becomes a [[TheStrategist strategist]], planning multiple escape routes, developing illegal skills, "collecting" money, and forming underworld ties. He also changes mentally, becoming capable of quick tactical thinking and rapid violence.
* In ''Film/AStrangerAmongUs'' a hard-boiled cynical cop goes undercover with a Hasidic neighborhood. While she is there, she temporarily falls in love with a Rebbe's son but is parted because of an arranged marriage. During this the cop learns to become more vulnerable and sensitive. The Rebbe's son also changes a little; at least he develops a sense of assertiveness that allows him to [[BigBrotherInstinct protect his sister]]. However the Rebbe's son is mostly a FlatCharacter and changes little. At the least he remains completely loyal to his heritage and goes through with the marriage in a context where other movies might have had him running off with the cop.
* Private Eye Eddie Valiant from ''Film/WhoFramedRogerRabbit'' starts off as an alcoholic with a deep hatred for toons (with respect for some) due to his brother being murdered by one. His adventures with the titular character has let go of said hatred and even regain some of his lost humor.

* Edmund in ''Literature/TheLionTheWitchAndTheWardrobe'' goes from being the obnoxious, spiteful sibling to being King Edmund the Just, kind, helpful and loving after he betrays his brother and sisters.
** Eustace Scrubb also goes through similar CharacterDevelopment.
* In ''Literature/AnansiBoys'', by the end of the book, the two main characters have switched many main personality traits, [[spoiler: and the endings you would assume from the beginning]].
* In ''Literature/ASongOfIceAndFire'', you can generally tell how long a character will survive by how willing they are to change:
** [[spoiler: {{Sacrificial Lion}} Ned Stark is the character most unwilling to compromise his beliefs, and dies by the end of the book]]; Jorah Mormont [[spoiler:stays by Daenerys' side for three books after his objectives change]], but his unwillingness to admit he was wrong gets him [[spoiler:banished from her presence]]; Tyrion Lannister's character changes subtly as he survives impossible odds; Sansa Stark has gone from {{Too Dumb To Live}} [[TheScrappy Scrappy]] to one of the characters most likely to survive to the end, because she slowly - yet frequently - learns from her mistakes.
* ''Literature/DonQuixote'': Sancho Panza and Don Quixote are dynamic characters that influence each other and end closer to each other in personality at the end of Don Quixote's adventures.
* The changes in Neville Longbottom, of the ''Literature/HarryPotter'' series, are subtle, but major, and can sneak up on you if you weren’t paying attention. He goes from TheDitz in the first book (whose only distinguishing characteristics are being timid, nervous, and forgetful) to the {{Badass}} leader of LaResistance at [[ANaziByAnyOtherName Death Eater]]-[[DoesThisRemindYouOfAnything Occupied Hogwarts]] in the seventh book. The change becomes most apparent in book five, when Neville, who flounders in nearly all his classes and “can barely stand a cauldron right way up”, becomes the fastest-learning member of the DA and attempts to fight in the battle at the Ministry.
** Hermione also undergoes some pretty big changes. She starts off as a bossy, insecure, neurotic, rule-abiding little girl, best exemplified by equating being expelled from school with ''being killed''. Ultimately ends up with a number of ToBeLawfulOrGood decisions, and chooses to be good -- beginning with her lying to Professor [=McGonagall=] about going after a troll in order to keep Harry and Ron out of trouble.
** Harry changes ''a lot''. At the start he was an inexperienced newcomer to the wizarding world who had a naive view on how the world works (i.e.Gryffindor = good, Slytherin = bad). With the harrowing adventures he is forced to endure, Harry not only transforms into a powerful and hardened wizard, but also learns that not everyone is as good or bad as they first appear.
** Ron's growth happens in the seventh book. Being forced away from the comforts of home has him not only grow out of his immature tendencies to facing his deepest and greatest fears.
* ''Literature/GalaxyOfFear'' started off as a FollowTheLeader to Goosebumps, but [[RecycledINSPACE Recycled IN STAR WARS]] - a twelve and thirteen-year old thrust repeatedly into a wide variety of disturbing circumstances. The main difference is that the series stuck with those two characters, and their aloof uncle, for the entire twelve-book run. Each of the three change significantly during that time while remaining recognizable. Tash and Zak stop being so attached-at-the-hip and develop separately while remaining close, they come to trust their uncle who comes to like and trust them, and each of the three becomes a little GenreSavvy.
* Compare all the main characters in ''Literature/{{GONE}}'' from their first appearance to their last appearance. They will almost definitely- for better or worse- be completely different people. This can both serve as a CrowningMomentOfHeartwarming (in the cases of Orc, Astrid and Quinn) or can be a TearJerker (see Diana, Caine, Hunter, etc).
* Daniel in ''Literature/TheLeonardRegime''. In the beginning, Daniel is young and rather immature. But as the story moves on, his outlook on things becomes darker and more mature.

[[folder:Live Action TV]]
* Basically everyone in ''Series/BuffyTheVampireSlayer'' has so much trauma inflicted on them that by the end of the show they've all become much, much darker. The only one who barely changes is Joyce, [[spoiler:and she dies in Season 5]].
** Buffy: Starts the series cheery, sometimes depressed but generally upbeat. Ends it basically broken, having lost her mother, died, gotten dragged out of heaven, gets thrust into a war she never asked for and then epically fails when expected to lead people.
** Xander: Starts out pretty much cheery and non-serious. Ends it much less cheery, much more serious and one eye short.
** Willow: Starts out shy, kinda upbeat but afraid of interaction. Ends it having lost the person she loved, went evil and had the guilt of murdering someone and has lost most of the self-confidence she built up throughout the show.
** Dawn: Loses her mom, loses her sister, her sister comes back and basically ignores her and is commonly ignored by the Scoobies. Oddly enough, she comes out of it actually better than when she went in (she tazed Xander WHILE he was driving, that's both crazy and brave). Still, what she went through through a lot of her existence could be called one prolonged moment of BreakTheCutie.
** Giles: Admittedly, he actually pretty much improves through the series, but he loses his girlfriend and then Season 7 (and 8, but I'm talking about show development since more people know that) shatters his father/daughter relationship into tiny little pieces.
** Spike: While, again, he doesn't change ''as'' much as others, he does go from an evil, soulless vampire to a anti-heroic vampire with a soul who [[spoiler:sacrifices himself to save the world (and comes back from it)]].
** Faith: Starts out acting happy and cheerful to hide pain, ends up mostly showing it on the outside by the end (but actually being more happy and cheerful). She went through a FaceHeelTurn in Season 3 before being put into a coma by the end of the season. She got better from both of these and eventually turned herself into the police. In the last season, she broke out of jail to help save the world. Come season nine she is considered by some InUniverse as more of TheHero than Buffy.
* ''{{Series/Angel}}'' also has quite a few:
** Wesley is probably the most triumphant example - he goes from a prissy comic relief Watcher on ''Series/BuffyTheVampireSlayer'' to a ruthless and badass AntiHero.
** Cordelia starts out as a typical AlphaBitch DefrostingIceQueen and ends up as TheHeart and the group's moral center. By season 3 of ''Series/{{Angel}}'', she's practically unrecognizable.
** Angel himself, in the beginning of ''Series/BuffyTheVampireSlayer'', is content to watch her kill baddies with an occasional cryptic message. Then he gets his own show, becomes a brooding HurtingHero, almost falls to the dark side several times and prevents a few apocalypses.
** Not to mention minor recurring character Anne Steel, who over five episodes (two on ''Buffy'', three on ''Angel'') goes from BrokenBird without a name of her own to self-confident founder of a refugee centre. Faith's core change also occurred partially on this show. As did Spike, in the last season. Simply put, those who played a prominent role in the spin-off ended up with even more change and growth than when they were on the mother-show (which, as stated, also had development). Creator/JossWhedon is evidently ''not'' very fond of the StaticCharacter trope...
* Topher from ''Series/{{Dollhouse}}'' is a very morally ambiguous HollywoodNerd at first... who performs a [[spoiler:HeroicSacrifice to save the world]] in the finale.
** Adele Dewitt begins as very cool and collected. Though by the end she still maintains her class, she's become much more warm, loving but also insecure.
** And of course, we need to have a moment for all the Dolls, who basically managed to ''invent'' new personalities from scratch. Especially Echo.
* Rachel Berry from ''Series/{{Glee}}''. She can't seem to get rid of her basest flaws of being abrasive and attention seeking though, but even those stem from her rather heartbreaking loneliness and lack of self esteem.
** Quinn, who starts out an AlphaBitch[=/=]TheCheerleader[=/=]BlondesAreEvil stereotype but eventually grows to caring about her baby and learns through her mistakes and her new friends in Glee club. After her pregnancy though she seems to have gone into denial and is trying to rebuild her old life and is a cheerleader again.
* Albert from ''Series/TwinPeaks'' undergoes a drastic change in personality after some sort of enlightenment experience.
* Carlos from ''Series/DesperateHousewives'' starts out as a neglectful husband, but eventually turns into a basically decent guy with a few flaws.
* Vala from ''Series/StargateSG1''. From cool one-off character to {{The Scrappy}} to a very pregnant plot point to a funny and interesting character that a large group of fans wanted to end up with their favourite [[{{TheWoobie}} woobie]] Daniel.
* In the first two seasons of ''Series/MyNameIsEarl'', Earl goes from a greedy criminal JerkAss motivated by a misinterpretation of the concept of karma to a genuinely selfless person.
* Probably one of the most subtle and realistic depictions of this is in ''Series/MalcolmInTheMiddle'', with Francis. Over the course of six years, Francis goes from a dangerously reckless teenage maniac setting cars on fire, sleeping around all over the school, and piercing every available inch of his face, to a loving and faithful husband with a steady job, who is willing to risk his health and reptutation to do the right thing. It was never a huge leap or a contrived epiphany - every episode, he grew up just a little bit, and suddenly, he's the kind of man you would trust to watch your daughter, ''and'' your money.
* ''Everybody'' on MadMen. Especially Pete and Peggy.
* Boyd Crowder of ''{{Series/Justified}}''. [[spoiler:In the span of a season, he goes from EvilCounterpart to WorthyOpponent to what seems to be a genuine (if possibly temporary) HeelFaceTurn in the season finale.]][[spoiler:Even though in season two he goes back to being a criminal, he is no longer as reckless and carefree as he was at the beginning of the series]]
* Bulk and Skull from the Zordon-era ''Franchise/PowerRangers'' shows. Over the course of six seasons, they start off as low-competence comic relief guys with no positive qualities who regularly bully the main characters and wind up ''leading mankind's IAmSpartacus rebellion against their alien conquerors'' at the end of ''Series/PowerRangersInSpace''.
* ''Series/StarTrekTheNextGeneration:'' Picard was somewhat dynamic at least by that show's standards starting out as overly stern and grouchy hating children but softening in later seasons and eventually bonding with children on the ship[[note]]that episode when he got de-aged in a transporter mishap might have helped.[[/note]] and having a family in a simulated reality. The ExpandedUniverse takes this trend to his logical conclusion and sees him actually settle down and start a family of his own.
** Spock grew a little throughout his run, first trying to purge his humanity and become wholly Vulcan but later moving beyond logic leading to his line "Logic is the beginning of wisdom, not the end."
* All the characters on ''Series/{{Community}}''. Troy goes from JerkJock to a geek with a strong sense of responsibility. Britta goes from ComicFoil to a broken husk of a woman. Jeff is probably the most dramatic example - in the first episode, he's a lazy sociopath who works as hard as possible to avoid doing any work whatsoever and only cares about the group as a way to have sex with Britta. In the last episode of season 3, he's caught between wanting to help Shirley with her case and wanting to study for his final exam. The transition between the two is incredible.
* Both Mulder and Scully from ''Series/TheXFiles'' are dynamic characters. They are very different characters at the beginning of the series than they are at the end, especially Mulder. In the Pilot, he is introduced as a brilliant but troubled loner. He prefers the company of his files to actual people, and spends more time in his office than his own apartment. He is deeply traumatized by the abduction of his sister decades before, plagued by nightmares and guilt. His quest to find her and uncover the Truth consume him to the point of near insanity. He believes in pretty much everything supernatural, so long as it's not religion. He is reactionary, reckless, and hostile to anyone who dares invade his space. He's also pretty self-loathing and arrogant. By the end of the series, he is a very different character. He's let Scully into his life in a big way; she functions as his LivingEmotionalCrutch and that actually helps him get over a lot of his issues. He realizes her life is more important than his quest, and begins to see that there's more for ''him'' as well besides the X-Files. He still wants to find the Truth, but at that point, it's more for the good of mankind than his own desire. In season 8, he's fired from the FBI and forced to hand the X-Files over to Agent Doggett. And he's fine with it.
** This change in character is showcased in season 7's finale, "Requiem" which was written as the series finale before being renewed for an 8th season. The episode is based on the case from the "Pilot," and it takes place in the same location. In the Pilot, Mulder emphatically tells Scully "nothing else matters to me" than his quest to find the Truth. Seven years later, he admits that the personal costs are too high, that there has to be an end sometime.

[[folder:Video Games]]
* Neku from ''VideoGame/TheWorldEndsWithYou'' learns how to expand his horizons and reach out to other people.
* Franchise/ResidentEvil has several:
** Leon S. Kennedy starts out as a rookie cop. He's naive and brash, with a strong sense of justice. He assumes the best of people he's just met. He then joins SOCOM. He's still trusting, somewhat, but he starts to become a bit jaded. He didn't want Manuela to kill herself from blood loss during the [[spoiler: fight with Javier, despite the fact that she's infected.]] But he expressed shock [[spoiler: that she didn't mutate.]] He ends up in the Secret Service. He's much more jaded and sounds more bitter than before. He still cares about others, to the point of yelling in woe over the deaths of two people he's known for roughly a few hours and ten minutes respectively. Instead of being thickheaded when [[spoiler: Krauser ended up a traitor]], by claiming he wouldn't switch sides, he just takes it as it comes, unlike in VideoGame/ResidentEvil2 with Ada. Skip ahead a year, and he looks like he's about to shoot his old friend [[VideoGame/ResidentEvil2 Claire]], a United States senator, and a little girl named Rani. He's jaded. He doesn't assume other people have good intentions. He still saves survivors, but he looks like he might kill them. By the time of Anime/ResidentEvilDamnation Leon has no more trouble with letting people die, wether they are good or evil. All he cares about is fighting the infection and finishing his mission no matter what order he's given, and he acts like a total jerkass most of the time.
* [[VideoGame/TheKingOfFighters Athena Asamiya]]. Although her personality didn't received such a big overhaul as her wardrobe, naturally. '''EVERY''' single new King of Fighters tournament features her either with a new stance or new outfit... save for XIII which gave her only a new color scheme and nothing else.
* Sagat of ''StreetFighter'' fame fits this, which is highly unusual for the "stuck in time" nature of the SF-verse. He starts out as the feared and proud Emperor of Muay Thai and World Champion. By the second game, he's an obsessed, broken man, desperate for revenge against Ryu. He joins Shadowloo for the mere promise of his vengeance. By the end of the Alpha series, Sagat witnesses just how far revenge has driven him, and realizes the emptiness of it. He rejects Shadowloo, helps Ryu, and even willingly loses to ''Dan Hibiki'' just to cure ''him'' of his thirst for revenge. By SF III, Sagat is a mature, noble fighter once again, considering Ryu an "old friend", and how he fights for the joy of it.
* Ezio Auditore of ''VideoGame/AssassinsCreedII'' starts off as a cocky, young Florentine noble without a care in the world. This suddenly changes when his father and two brothers are wrongly executed by a corrupt government. He is then forced to take up his father's assassin mantle and go on a brash, rage-induced RoaringRampageOfRevenge. Over the course of the game and it's [[VideoGame/AssassinsCreedBrotherhood first sequel]], he matures into a calm, wise tactician. Taken further in the [[VideoGame/AssassinsCreedRevelations second sequel]], where he seems to have a plan for nearly any person or situation he may come across. In addition, Ezio's saga covers nearly ''fifty years'' of his life, starting with him at seventeen years old and ending with him finally passing away at sixty-five.
** Altair of the first game also gets this by ''Revelations'', despite his limited screen time. He starts off as a normal assassin that is committed to his order, grows arrogant upon making Master and spends the rest of his own game learning where he went wrong and growing calmer, more insightful and wiser. ''Revelations'' takes this a step further where his whole life is shown, drawing him in clearer colors and showing his growth from an arrogant young man into a wise and strong leader in more depth.

[[folder:Web Comics]]
* ''Webcomic/TheInexplicableAdventuresOfBob'' has some interesting examples of CharacterDevelopment, in that at least four of the characters are artificial beings born as near-[[BlankSlate blank slates,]] and we get to see them evolve. The most dynamic has been [[CloningBlues Galatea,]] born a [[ChildrenAreInnocent complete innocent,]] turned [[WoobieDestroyerOfWorlds hyper-paranoid]] by an [[FreudianExcuse awful childhood,]] then [[TaughtByExperience calming down]] and settling into a rather sophisticated lifestyle in [[GayParee France]] (funded by [[ClassyCatBurglar theft)]], and now she has unwittingly become a [[EvilMinions minion]] to the comic's BigBad.
* In ''Webcomic/GunnerkriggCourt'', Annie has already changed rather dramatically--transforming from a friendless EmotionlessGirl to an outgoing [[http://www.gunnerkrigg.com/?p=854 goofball]]--and the story isn't even over yet. She's basically a DefrostingIceQueen boosted UpToEleven.

[[folder:Web Original]]
* In ''WebVideo/MarbleHornets'' it is suspected that Alex, the missing film student, is changed from a basically reasonable, stable individual into a paranoid obsessive due to the influence of [[SlenderManMythos the Operator]]. [[spoiler: Recent entries (as of July 2011) suggest that Alex is now working for, or somehow allied, with the Operator.]] The reasons behind this remain obscured at this time.
** Meanwhile, Jay (another student searching for Alex) has at least moderated his characteristic GenreBlindness by beginning to trust the people around him a little less unconditionally. [[spoiler: Or at least he is during the seven month LostTime period.]]
* WebVideo/TheNostalgiaChick has evolved from "Lindsay acting like the Critic" to a pathetic, nuanced, sympathetic failure of a human being. While it might not sound like a good thing, ask yourself, how many female characters do we have like that?
** And speaking of, WebVideo/TheNostalgiaCritic. He went from a stereotypically manly, whiny jackass who took things too seriously to a broken husk of a man who's still strong-willed, endearing and a major PapaWolf.

[[folder:Western Animation]]
* Zuko has quite the character arc throughout ''WesternAnimation/AvatarTheLastAirbender''. He began as a bitter and angry WellDoneSonGuy. After a long period in the HeelFaceRevolvingDoor, he realized he could earn his own honor. He became more friendly, peaceful and wise.
** A lot of characters did this. Aang went from a happy-go-lucky kid to a responsible [[MessianicArchetype hero]].
** Sokka developed from his original comic relief role, and overcame his insecurities to become a BadAssNormal and tactician.
** Katara turned from an eternally optimistic and sweet girl into someone much much more pragmatic and hardened by the difficulties of war.
* ''WesternAnimation/TheLegendOfKorra'' has this in a lot of characters, major and secondary.
** The title character, Avatar Korra, starts off as HotBlooded, impulsive type who would always use brute force and violence to get her way. By the end of the series she has become a more level-headed young lady who will opt for reasoning with an antagonist instead of going with violence first.
** Tenzin, Korra's airbending mentor and Aang's youngest son, learns not to compare himself to his father and to just be himself.
** Bolin goes from an immature, InnocentlyInsensitive goof who was always following in his older brother's shadow to a mature, serious young man whose has become his own individual.
** Although most of his growth is off-screen, Mako becomes an AllLovingHero by Book 4, a sharp contrast to the cynical person who only cared for money and Bolin he was in Book 1.
** Wan, the first Avatar, went from being a petty but well meaning thief to the enduring BigGood of the whole world.
* Eric the Cavalier in the ''WesternAnimation/DungeonsAndDragons'' cartoon goes from the most cowardly, selfish member of the group, to the one most likely to charge into the enemy to protect his friends.
* Most of the cast of ''ThomasTheTankEngine'' in [[TheRailwaySeries the original books]] as well as the classic episodes. Thomas himself started off as a cocksure, immature young station pilot with the delusion that no engine worked harder than he. But he learned from advice and his experiences to be responsible, earning his own branch line and eventually becoming a wise engine in his own right. Gordon learned to be less condescending towards other engines, and he, Henry, and James all learned not to complain about shunting and dealing with goods trains.
** The later episodes fluctuate with this, especially due to heavy use of the SanityBall. Thomas for example is still a lot more altruistic and humble than before, but also more careless and something of a CloudCuckooLander. James also goes from being more kind natured and helpful to other engines to an even bigger narcissist than before, DependingOnTheWriter. In contrast some of the more mature engines gained more defining flaws in later episodes (Toby for example went from a conventional StraightMan to more timid and insecure).
* Utilized to a subtle but effective length in ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', all of the [[IncrediblyLamePun mane]] characters, while maintaining most of their defining flaws and characterizations to some extent, have matured slightly and become more flexible.
** Twilight Sparkle in particular started off aloof and uninterested in socializing to a warm leader who cares deeply about her new friends and community.
** Rainbow Dash went from resenting her weaker comrades to nurturing and motivating them (particularly noticeable in her treatment of Fluttershy),
** Applejack became less prideful and more willing to accept help from others.
** Fluttershy has gone from not being to stand up to ''anyone'' to knowing how and when to put her foot down.
** On the other hand, Rarity hasn't changed much, aside from learning to treasure her friends, sister, and [[EmbarrassingNickname Spikey-Wikey]], though she was arguably the most mature to start with. And Pinkie Pie is... well, [[{{Cloudcuckoolander}} still]] [[NoFourthWall Pinkie]] [[RealityWarper Pie]].
* Seen very well in WesternAnimation/YoungJustice;
** Wally West/Kid Flash matured from a joking, flirtatious, very light-hearted character who refused to admit feelings for Artemis, to someone much more serious, responsible and a dedicated boyfriend.
** Artemis, on her part, started off very much as a BrokenBird, with serious trust issues and way more insecure than she let on. By the end she'd come to trust her friends and was much more confident.
** Superboy changed from basically a big ball of rage into someone much calmer and collected, even becoming something of TheHeart to the team.
** M'gann started off as TheCutie, though it later became revealed that she was more of a deconstruction of said trope. She grew more ruthless and pragmatic as time went on, and eventually had to be snapped off course by a MyGodWhatHaveIDone moment.
** Dick/Robin/Nightwing meanwhile changed from a playful trickster who was ''afraid'' of becoming like Batman to someone almost just like him.
* Both Ratchet and Prowl of ''WesternAnimation/TransformersAnimated'' started out as a resigned veterans of the Great War who used grumpiness and aloofness to avoid getting attached to their crewmates and temporary home. By the end of the series, both have become much more invested in their teammates and their adopted home.
* TransformersPrime has several cases:
** Jack initially [[RefusalOfTheCall walks out]] on the Autobots, saying it is too dangerous. He is brought back because Arcee isn't ready to say goodbye, and stays around for a while just to keep Miko and Raf safe. By the middle of season one, he has saved the team a few times, went one-on-one against one of their most dangerous enemies, and has proven his worth several times over. By early season two he is well established as the team's BadassNormal.
** Ratchet goes from mild distaste for human company and complaining about babysitting duty ("If they get underfoot, they will go squish.") to being a bit of a father figure to the kids, especially Raf. In the finale [[spoiler: he decides to stay on Earth instead of returning to Cybertron with the others.]]
** Miko starts off as a naive borderline-LethallyStupid RecklessSidekick who doesn't realize she's a liability to the team. After some traumatizing experiences, she matures... somewhat.
** Wheeljack and Ultra Magnus, together, sort of dynamic into each other. Wheeljack shows Ultra Magnus how effective his unconventional methods can be, while Ultra Magnus shows Wheeljack how important discipline can be. They go from TeethClenchedTeamwork to BashBrothers over the course of season 3.
* Hank Pym of ''WesternAnimation/TheAvengersEarthsMightiestHeroes'' begins the series as the optimistic Ant-Man who truly believes that science can make the world a better place and that conflict can and should be resolved through with words rather than violence. His experiences with the Avengers pushes his beliefs to their breaking point, ultimately he ends the series as the much more cynical and hot-headed Yellowjacket.
