History AdaptationalHeroism / FanWorks

* ''WebOriginal/Brighthammer40000'' is a LighterAndSofter take on ''TabletopGame/Warhammer40000''. Naturally, examples of this abound.

* In ''FanFic/JusticeLeagueOfEquestriaGodsAndMonsters'' the MLP cast take the roles of certain DC characters, however certain villainous characters are given more heroic personalities, for example:
** Toyman & The Trickster(Button Mash and his mother). Who are basically Anti-Heroes out for revenge and aren't interested in committing crimes unless they somehow hurt Black Mask's business. When Black Mask is finally killed they retire, ''steal all of his money'' and relocate to another city.

* ''FanFic/KingsOfRevolution'' has some examples:

* In ''FanFic/TheLastDaughter'', [[spoiler:[[Franchise/{{Superman}} Zod]] goes from a cruel general to helping Jor-El get Zara off of Krypton]]. He himself doesn't and gets killed when Krypton explodes.

* In the Bleach/Madoka fanfic ''[[https://archiveofourown.org/works/30333318/chapters/74772423 Moebius]]'', has [[spoiler: Kriemhild Gretchen]], who instead of a world-ending Witch is the benevolent Goddess of the Quincy.

* ''FanFic/TheStalkingZukoSeries'':

* ''FanFic/BTVSSeasonsRewrite'': In canon, Spike went through the HeelFaceRevolvingDoor and didn't truly begin to redeem himself until Season 5. During the Season 4 rewrite, he's considerably more heroic and actively helps the Scoobies out against Adam.

* In ''Fanfic/PartOfTheNight''- an AU of ''Film/TheDarkKnightRises''- Selina is depicted with much more of a spine than in Film/TheDarkKnightRises. Rather than let herself be intimidated and manipulated by Bane, and be complicit in murder or terrorism, she chooses to help Bruce with stopping Bane so she can get herself and her sister out of the criminal life.

* In [[https://www.fanfiction.net/s/11767392/1/Frigid-Future Frigid Future]], Salza acts as a NobleDemon who [[HeroicSacrifice willingly volunteers]] to be Cooler's sparring partner so that Cooler can become stronger, despite knowing full well that all that waits for him are several [[NoHoldsBarredBeatDown No Holds Barred Beatdowns.]] Cooler even says that he won't show Salza any mercy, but he doesn't care. Even Gohan and Cooler were impressed by that.

* ''FanFic/FalloutEuropa'': The Brotherhood of Steel is much less ambiguous as they were in ''Fallout 4'' which likely comes from the fact that, with the threat of a giant Super Mutant army closing in on all human settlements, they have a much clearer enemy to fight.

* In ''Literature/HarryPotter,'' Marge Dursley is Vernon's sister and acts ''even nastier'' to Harry than the Dursleys. [[https://www.fanfiction.net/s/5165369/1/My-Nephew-Harry My Nephew Harry]], a fanfic by Creator/{{Lucillia}}, gives her more understandable motives for her nastiness. She is portrayed as having been hardened by her [[FreudianExcuse own upbringing]] into a woman who supports ToughLove. She thus mistreats Harry based on the lies told by Petunia and Vernon. When she learns the truth, she hits the wall and starts giving Harry the love he deserves.

* ''FanFic/BurningBridgesBuildingConfidence'' has [[WesternAnimation/MiraculousLadybug Chloe]] working to [[TheAtoner redeem herself]] rather than assuming that her stint as Queen Bee proves she's worthy of being a superheroine. While not particularly interested in mending fences with her classmates -- at least not while they're all [[GullibleLemmings fawning over]] a ConsummateLiar like [[BitchInSheepsClothing Lila]] -- she isn't bullying them anymore, and has reached out and tried making amends with others. Including Marinette, with whom she's tentatively built up a nascent friendship even before [[NewTransferStudent Cole]] shows up. She also openly acknowledges that since she outed herself to all of Paris, trusting her with the Bee again would be a risky move.

* In ''Fanfic/PerfectionIsOverrated'', the story diverges from canon around the time the Himes are manipulated into attacking Nao. As such, Nao and Shizuru do not undergo their [[FaceHeelTurn Face Heel Turns]] as in canon, [[spoiler:until one of the [[ParodySue SUEs]] alters their personalities, resulting in Natsuki having to fight each of them]]. Nao ends up as an AntiHero who ultimately ends up questioning herself and [[TookALevelInKindness taking a level in kindness]], and while Shizuru finds herself [[{{Gayngst}} doubting herself over her feelings for Natsuki]], she ultimately comes to terms with them.

* In ''FanFic/TheFlashSentryChronicles'': Trixie starts the same way she did in canon, as a traveling show-mare who lied about her achievements to make herself look better and show off. But, thanks to being saved by Flash from some crooks earlier, she opens up to him and his friends and helps them stop the group of crooks that attacked her. She decides to better herself, and later becomes the apprentice of Princess Luna.

* This trope is half the premise of ''FanFic/TheRainsverse'': Chrysalis and Sombra are (as far as we can tell) [[BigGood Big Goods]], and the six Knights of Harmony are all ponies who were villains in the Celestiaverse.

** Kid!Ino displays great if foolish bravery by defending kid!Naruto (whom she still despises) from [[spoiler:his Uchiha kidnapper]]. She goes as far as to form the trademark Yamanaka hand seal with the intent of overtaking the mind of the attacker -- an adult kunoichi.
** Kid!Sakura, after watching her friends being kidnapped, requests the first ANBU she encounters to rescue them. She supplies said ANBU with very valuable information and is willing to accompany him wherever her friends are being held captive.

* ''FanFic/WarOfTheBiju'': [[spoiler:[[DecompositeCharacter In this fic, Obito was never designated as Madara's successor and thus is not Tobi. The Tobi in this fic kills him for his eye, preventing him from ever making a]] FaceHeelTurn. Obito's heroism is firmly established when Kabuto revives an artificially aged-up version of him during the war and forces him to fight against Kakashi and his batallion]].

* ''FanFic/SVWishes'' has its transmigrators act out on their more altruistic desires since they aren't being forced by the System to stick to a narrative.

* In ''FanFic/SonicXDarkChaos'', the Metarex were changed from a group of faceless robots trying to destroy the galaxy to a group of {{Well Intentioned Extremist}}s who want to kill Tsali and rebuild the Seedrian species by any means necessary.

[[AC:''VideoGame/{{Touhou}}'']]

** Felix is more in-line with his JerkWithAHeartOfGold self from the original preview. [[spoiler:It's later revealed that he is the hero Lord Winter as well]].

* ''Fanfic/GoneBattySefiru'': Oda Jun used to be part of a gang that sells girls into sexual slavery, and then finds out that one of the girls he sold is the younger sister of his newest boss. While in canon he keeps this a secret and tries to kill the sister and Kiryu to keep his boss' attention all to himself, in this fic he has a HellRealization. He decides to tell everything to his boss, so he [[FaceDeathWithDignity puts on his best suit]] and [[RedemptionEqualsDeath gets ready to die]]. The boss doesn't kill him because [[CantKillYouStillNeedYou Oda has the most info on her location]], but he indulges in ExtremeMeleeRevenge. Oda remains a steadfast ally of the heroes afterwards.
