Adaptational Badass: Fan Fiction

Fan Fic writers love to make their favorite characters far more badass when they're the ones writing them.

Backyard Sports

  • Stephanie Brown in Macushla. 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).

The Black Cauldron

Calvin and Hobbes

Cross Over

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 builds him up into 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.

Final Fantasy VII
  • Kunsel is a normal Second Class with being a well informed and vaguely gossipy Mr. Exposition as his distinguishing trait and doesn't stand out in a company with the likes of Sephiroth and Zack Fair. In the The Fifth Act, he is shown to match Zack in skill when given the motivation and to be far more perceptive and knowledgeable than people realize. Kunsel is upgraded to being a powerful Knowledge Broker having a vast information network, being everyone's go to guy for information and in the Omakes, being better informed than the Turks.

Harry Potter
  • Harry Potter and the Methods of Rationality:
    • 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 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 an 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.
  • Cruciamentum Eternus includes Lucius Malfoy during the time period of the last book. In the canon he was broken, pathetic, weak, and didn't fight Voldemort until it was safe to (and Narcissa pushed him). In this story, Draco's murder has him secretly murdering Death Eaters from almost the moment he's released from Azkaban, while still feigning allegiance to Voldemort's side, with the ultimate plan of killing Voldemort himself. If nothing else that requires at least an epic feat of Occlumency and a strength of will he never shows in the books.

Jackie Chan Adventures

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.

Kingdom Hearts

The Legend of Korra
  • While Korra was undoubtedly badass in canon, she is even more so in The Saga Of Avatar Korra, accomplishing or gaining 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, and delivering Curb Stomp Battles to characters who were more difficult for her to defeat in canon, such as Unalaq, Desna, Eska, and Kuvira.

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 (Fan Fic):
    • The Jewel Seeds get a serious upgrade in their power and threat level. As the author explains:
    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.
    • Pretty much all the characters over the age of about sixteen or so get a significant competence boost. 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, showing 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
  • 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.
    • There's also the CMC, who manage to be Badass Adorable in this universe, Minuette and Twinkle Shine, who really get to show off their Gifted Unicorn credentials, Shining Armor, who saved the world from an Imagination Demon, and Trixie who becomes the Sixth Ranger and grows to be able to fight Twilight on fairly even standing. Honestly it's easier to count the characters that don't count.
  • 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 Vapors because she was found by the Third Hokage and adopted into the Uzumaki Clan as well as studying under Anko, Karin here is capable of holding her own with Sasuke in combat and is often paired with him on missions.
    • In canon Konan got caught by Jiraiya, acted as support during Pain’s attack on Konoha, and got killed by Tobi. Here she demonstrates exactly why she’s The Dragon.

Neon Genesis Evangelion

  • In canon, Kousaka Kyousuke is the type of person who lets his sister walk all over him. Contrast this to My Life Can't Lose Its Normality where he (as well as Ayase, Akagi, and Miura) are a team of martial-arts mastering, Yakuza-killing vigilantes who pull off stunts normally reserved for paramilitary organizations and special operatives.

  • 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
  • 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:
    • 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 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.

Super Why!

Sword Art Online
  • In The Kirita Chronicles Kirita, the Gender Flipped version of Kirito, is more capable of being able to defend herself in the real world than he could. 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 for example makes her into a Walking Wasteland and a Fallen Angel, whereas in Touhou Nekokayou she's slightly more powerful but still comic relief.
  • Imperfect Metamorphosis:
    • Kotohime 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 point she delivers a beatdown to Marisa Kirisame for disintegrating one of her officers (she got better).
    • Yuuka Kazami in canon is certainly powerful and has aspects of The Dreaded, but there are plenty of characters who could take her in a fight. Yuuka in IM is the most feared being in Gensokyo's history, a nightmare who no-one dares confront directly, and who shrugs off all the attacks leveled at her by Yukari and her team she assembled specifically to kill Yuuka, in the process revealing her nature as an Outer God.
  • Mokou is already an immortal powerhouse and EX-Boss. Touhou Ibunshu in addition 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.
  • Maiden's Illusionary Funeral takes Yukari and Ran, already ancient sages with near-unsurpassed abilities, and makes them both The Juggernaut who cleave through groups of specialist youkai hunters without a scratch. This in turn makes Yuyuko one as well, given she nearly killed Yukari while still trying to restrain her powers.

  • 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.

Young Justice
  • In Young Justice Titans, the Scarecrow gets a serious badass bump. Thanks to becoming a member of the Church of Blood, he's given supernatural powers, and is hinted at being essentially a real living scarecrow now, with impossible flexibility, his Sythe that he pulls out of his mouth, and fear gas in both Gas and solid forms. He's even able to fight a team with powers far beyond him (including a green lantern might I add), though their relative inexperience is probably why they struggled to try to put him down. He's also almost unkillable too.
