Adaptational Badass: Fan Fiction

Backyard Sports


  • In the fanfic Macushla, Stephanie Brown becomes one: after her father is killed for unknown reasons by the league of shadows, she's taken to serve under Talia al Ghul. She's a master assassin before she's 18 years old and becomes Damian Wayne's bodyguard/Morality Pet. (After Talia fakes Stephanie's death and sends her away because she and Damian were too close, he leaves the League and asks to join Dick Grayson of his own will).

Death Note

  • Do you hate how Myotismon Digivolves into Malomyotismon in Digimon Adventure 02 and is built up into a major threat only to be dealt with in the most pathetic way possible by Talking the Monster to Death? Well Zero 2 A Revision is here to change that, now he is built up into a major threat and is really a major threat thanks to all of his schemes and planning. His power is so great that even the Time Master Xeedmilleniummon and the Guardian Beasts will fall before him. To defeat him, the Digidestined and their Digimons fused together and after a long battle, in the end managed to defeat him. To commemorate this evolution, Malomyotismon's name is changed into a more intimidating name Belialmyotismon (Apparently the author associates Malo with mayonnaise).

Harry Potter
  • Everyone in Harry Potter and the Methods of Rationality gets an upgrade from their canon roles:
    • Severus Snape has been spiking Lord Voldemort's father's grave with every dangerous drug and poison known to wizardkind (and LSD—because it might affect him), as well as every other grave in the cemetery on account of Voldemort might have moved the gravestone, and the graves of every other ancestor of Voldemort's that he and Dumbledore could track down, just in case. Too bad Voldemort foresaw this contingency and, since he couldn't move his father's bones if he wants the resurrection spell to work, moved the entire rest of the cemetery to an entirely different location and memory-charmed the local Muggles.
    • Harry Potter, in so many ways. Here's his following plan:
    • Draco Malfoy went from The Bully to the following roles: Manipulative Bastard, The Starscream to Harry, and scion of a long, proud line of Men Behind the Man.
    • Quirrell in canon is a simpering stutterer who's a host to Voldemort. Word of God says this Quirrell is possessed by Voldemort, which now makes him the following: Evil Mentor to Harry, a sixth-dan in an unspecified martial art, and he horcruxed the pioneer probe! Oh, and then he went and tricked Harry into breaking Bellatrix Lestrange out of Azkaban.
    • Blaise Zabini went from Draco's crony to a quintupple agent in a war with only three sides.

Jackie Chan Adventures
  • Queen Of All Oni has the Samurai Khan. While in canon they're Fake Ultimate Mooks, here they're just as strong as they look, serving more as Elite Mooks.
  • In another Project Dark Jade story, Webwork, the Samurai Khan get the same treatment. There's even an explanation to how they were so weak in canon: their General wasn't properly bonded to his host, halving the Samurai Khan's power. They were also being poorly managed.

Kamen Rider Fourze
  • In Horseshoes and Hand Grenades, nearly every single character who ever appeared in Kamen Rider Fourze have gone into fighting mode. This ranges from Yuki Jojima using her Hayabusa Plushie as a boxing glove, Chuta Ohsugi fighting off his former love interest, Sarina Sonada and minor characters like the ones in the Amanogawa High Glee Club consist of a sword wielder, a samurai and a ninja.

The Legend of Korra
  • The Saga Of Avatar Korra: While Korra was undoubtedly badass in canon, she is even more so in this story and accomplishes or gains abilities sooner than her canon counterpart due to being raised and put through a Training from Hell regiment by the Red Lotus for fourteen years.
    • Without becoming Tenzin's student, she has some capability to airbend thanks to Zaheer's teachings, and she eventually is capable of flying a glider with some difficulty.
    • Korra delivers Curb Stomp Battles to characters who were more difficult for her to defeat in canon, such as Unalaq, Desna, Eska, and Kuvira.
    • In Chapter Fifteen, demonstrates two instances of Korra achieving something before her canon counterpart. Korra accidentally uses an airbening attack to stop Zaheer from killing Unalaq. At the end of the chapter, Korra enters the Avatar State for the first time in order to escape from the Republic City police.

Love Hina
  • Contract Labor: In direct contrast to the Extreme Doormat he was in canon, Keitaro actually has some backbone and is far more willing to stand up to and for the Hinata's residents, even managing to defeat Motoko in an honor duel.

Lyrical Nanoha
  • Game Theory does this for the Jewel Seeds.
    Aleph: Nanoha showed us that the Monsters of the Week could be a backdrop to the real meat of the plot, the character interaction, but then Madoka came along and showed us that the Monsters can still be legitimately, vividly scary. And Game Theory is very much a post-Madoka story, with the harsher rules and the scarier monsters and so on.
    • Also, pretty much all the characters over the age of about sixteen or so get a significant competence boost. Notably, they aren't any more powerful, but they use what they have much more effectively because they employ proper tactics. Especially Precia.
    • The Wolkenritter in particular have received a major upgrade in skill. They aren't any more powerful, but they show the experience and tactical acumen that would be expected of centuries old combat constructs.

  • Yukino in Perfection Is Overrated. In the original series, her Child was only good for surveillance, and left her easily defeated by Shizuru. In this fic, she realizes that while she's not the best in a straight-up fight, she can use her powers to tip the balance of power in her favor at crucial moments, such as when she incapacitates Shiho, enabling Mai to win her battle without Yuuichi dying, and when she, in the final battle, uses her Child's abilities to immobilize one of the last remaining SUEs' Child long enough for Natsuki to finish her off.

Marvel Universe
  • This trope is a staple for the villains of Ultimate Sleepwalker: The New Dreams and Ultimate Spider Woman: Change With The Light. Characters like 8-Ball, the Brothers Grimm, the Chain Gang and Jack O'Lantern were all C-lister villains, at best, in the original comics. In the Earth-2706 verse, though, they're exceptionally deadly threats, forming the focus of the Fics.

My Little Pony
  • From the Pony POV Series:
    • Mimic is said by Princess Luna to have been the first, and only, mortal pony to injure Discord, by kicking him in the face at supersonic speeds until she knocked his tooth out. He killed her afterwards, but still. Starsong probably also counts, managing to fend off Discord's brother Anarchy for a considerable time.
    • While Princess Cadence turned out to be pretty badass in canon, the version of her in this series was able to take on an avatar of Discord's father Havoc and not only survive, but it's implied that she won.
  • Rainbooms and Royalty has Zecora, while still being The Obi-Wan to the Mane Six like in canon, also proved personally fantastic repeatedly over the course of the series, with such highlights as saving Rainbow Dash from the Shadowbolts, fighting Nightmare Moon one-on-one, and saving Dinky, Pipsqueak, and Alula from King Sombra's bushwoolie Mooks.
  • Xenophilia turns Lyra Heartstrings into a grandmaster of the Still Way, the only Unicorn-exclusive martial art. She's described by Rainbow Dash as "probably one of the five or six most dangerous ponies in Equestria, even counting the Princesses," and the only pony in town other than Twilight who could beat her in a serious fight. Chapter 9 reveals her to be an auxiliary Royal Guard, and we also see her in action.
    Lero: Wow. I had no idea. She's always been really friendly to me.
    Rainbow Dash: (giggling) Yeah, I’ve heard that about her. Total sweetheart, you’d never guess that she could kill you in half a second from, like, three hundred bodylengths away.

  • In many Naruto fanfics, the title character and his Academy teacher, Umino Iruka, tend to get an odd power-up. In the manga, Naruto is painting on the monument in front of an assembled crowd of ninjas until Iruka calls him down. In the anime, Naruto manages to dodge two low-ranked Chunin in the first episode before his teacher appears behind him once he assumes the coast is clear. However, in fanfics, he tends to outrun and outmaneuver Chunin, Jonin, Anbu and even occasionally the Hokage, for hours, with Iruka being the only person able to catch him, usually within ten minutes of setting out. How Iruka catches the boy who makes Houdini look like an amateur is rarely explained. In certain fanfics, the author explicitly labels Naruto in the description as "Smart", "Strong" and/or "Godlike.

Neon Genesis Evangelion

Ore no Imōto ga Konna ni Kawaii Wake ga Nai

  • In canon, Ash Ketchum is a rather bumbling, childish, and well...stupid, trainer. In The Chosen One's Journey, all that is replaced with maturity, responsibility, discipline, and pure badass.
  • Due to the result of a Peggy Sue plot, Ashes of the Past has pretty much everyone that Ash has come into contact with become a bona-fide badass. This ranges from Ash actively pursuing his Aura Guardian training and fighting Pokémon with his bare-hands, to Charizard learning the Poké-equivalent of a tactical nuke, to Squirtle (as a now-Kamina expy) breaking the laws of physics on a regular basis.

  • RWBY Reckoning takes the normally bumbling Jaune Arc, a guy who is nothing like his legendary ancestors, and makes him able to build a functioning time bomb with approximately 18 flares, some duct tape, and some scraps. And it's powerful enough to shred the stomach of a very large Grimm.

Sailor Moon
  • Cosmic Warriors takes the normally cheesy Tuxedo Mask and has him wielding his cane like a real weapon with a hidden sword within. On top of that, his cane seems capable of more tricks, like shooting five rechargeable red thorn darts from the base. So far there haven't been any cheesy one-liners either.
  • Beautiful Destroyer Sailor Moon. Pick a main character, any main chracter.
  • Sailor Moon: Legends of Lightstorm: Sailor Moon now fights primarily with sonic screams powerful enough to annihilate buildings, her energy disk can slice through almost anything, and her physical strength is great enough to punch through rocket-proof armor.
    • Sailor Mercury impales things on gigantic ice spears and can stand up to the toughest of Negaverse drones single-handedly.
    • Tuxedo Mask has fighting skills that rival Lightstorm's can cut through virtually any substance with his razor-roses, hits hard enough to knock gigantic drones off their feet, and can withstand explosions strong enough to shred drone armor.

Sonic the Hedgehog
  • Sonic X: Dark Chaos pretty much turns everyone - especially the scrappies and weak characters - into utter badasses.
    • Tails goes from being a weak, shy Gadgeteer Genius into a Magnificent Bastard captain who gains a Lovecraftian Superpower and ends up saving the entire universe from an Eldritch Abomination at the cost of his own life.
    • Cream stays with Sonic and friends to the end, even after seeing things that would make most adults break down. In Episode 66, she and her chao Cheese ends up beating Astorath the Prince of Darkness on her own.
    • Cosmo saves several planets before becoming acting captain of the Blue Typhoon, and she is also appointed leader of the Metarex during the final battle. And in the rewrite, when Astorath and Beelzebub land on her ship, she runs out onto the flight deck with Venus' demon scythe and rips them a new one.
    • Chris Thorndyke may be the king of them. He goes from being a whiny, dependent brat to a Genius Bruiser, pulls off a Big Damn Heroes and unleashes Death from Above with the Typhoon in the rewrite of Episode 69, and later on fights Beelzebub and Astorath alongside Cosmo during the final battle.

Super Mario Bros.
  • Clash of the Elements: Cackletta wasn't really much of a threat in Mario & Luigi: Superstar Saga, being an unimpressive mage with an easy boss fight halfway through her game. In this story, on the other hand, she's a Manipulative Bastard of the highest degree, a two-thousand year old remnant of the Dark King's forces who caused the legend of the Shadow Queen just to extend her own life and she has also become a Chessmaster who successfully managed to outwit Big Goods, such as Alpha, the Star Spirits, and an omniscient trio of beings known as "the higher-ups". Implications exist to suggest she has also been able to control the Heartless.

Super Why!

Sword Art Online
  • The Kirita Chronicles: Kirita the genderbent version of Kirito is this because she has more capacity of being able to defend herself in the real world than he could. In this story, after quitting Kendo, she took up karate classes and is capable of delivering curb stomp battles to bullies and her fellow karate students. In canon, it is assumed Kirito focused solely on computers and video games. After being trapped in the video game, Kirita trains even harder to become stronger because she believes players will consider her vulnerable if they find out she is a female player.

Tengen Toppa Gurren Lagann

  • Rumia is lowest of the low in Gensokyo's hierarchy, weak and with a useless power. It's widely speculated however that she possesses a Superpowered Evil Side, meaning most fan works featuring her give her an appropriate power boost, though the degree of the boost varies vastly.
  • Imperfect Metamorphosis's take on Kotohime, who was a generally ineffectual and totally delusional combatant in her original appearance. In this Fic, she's graduated to the rank of Beleaguered Assistant to Yukari herself, running Gensokyo's first police force, and at one poit, she delivers a beatdown to Marisa Kirisame for disintegrating one of her officers (she got better).
  • Mokou is already an immortal powerhouse and EX-Boss. Touhou Ibunshu has her possess the powers of a Physical God, giving her the strength to go toe-to-toe with Yukari after creating an army of thousands of kashoyo.

  • In Worldwar: War of Equals, all of South America, Central America, and Eastern Europe put up much more of a fight than they did in the source material. Human tanks qualify as well. In the original novels, even the best Human tanks of the 1940s could easily be destroyed by a single Landcruiser. Thanks to tank technology advancing in the last couple of decades, our tanks are either equal to or superior to their Landcruisers.
