He Who Fights Monsters / Fan Works

  • General: Many a Mary-Sue Hunter becomes as much of a hollow Wish Fulfillment fantasy as the Mary Sue they were sent after.
  • A Crown of Stars: In an earlier chapter Daniel explained to Asuka that he fell into this a very long while ago, and during that time he made a lot of things he was not proud of, and it was thanks to his family that he managed to stop acting like the monsters that he was fighting. He says it's why he now focuses Avalon's efforts on helping and healing, rather than bringing judgement on the wicked (they still do the latter to some extent, but that's not where their primary interest seems to lie).
  • A Minor Miscalculation presents Isshin Matoi as a Well-Intentioned Extremist Anti-Hero rather than the solemn atoner he was in canon. Over the course of the war, he gradually becomes so driven to kill Ragyo, wipe out the Life Fibers, and protect Ryuko that he's willing to sacrifice anyone to do it. And then The Reveal in Chapter 23 sends him into full Villain Protagonist territory.
  • A central theme in Avatar: The Last Airbender Revised is preventing oneself from succumbing to He Who Fights Monsters by only killing when absolute necessary. This is present primarily in Katara's character arc, although it fits into those of others as well. A paraphrase of Nietzsche's quote is used as the Arc Words for the first three books to reflect this.
  • Children of an Elder God: The premise of the story is the Children fighting Cthulhu Myths' Eldritch Abominations and gaining their powers after slaying them, stopping being human gradually. Gendo stated that "they gazed into the abyss, and the abyss became them."
  • Child of the Storm has averting this trope as an underlying theme, as Harry's becoming more open and better with his emotions means that his former Suppressed Rage is... not so suppressed. Plus, since he's the son of Thor, part of the House of Odin (which is known for the Warrior's Madness), it's potentially even more explosive. And to make matters worse there's repeated implications that his mother, a cousin of Jean Grey's, invoked the Phoenix as his protection. This, in concert with his powers developing faster than he can control and the sort of things he faces, from petty everyday cruelties like the bullying of Luna Lovegood and the Dursleys treatment of him to grander scale evil such as that perpetrated by HYDRA, mean that more than a few are genuinely frightened that he'll turn into the next Magneto if not watched carefully. They include Harry himself, who is downright terrified of this trope, to the point where it stunts the telepathy side of his Psychic Powers, since he's scared witless of what he might do with them.
    • Then he gets over it by the early parts of the sequel, Ghosts of the Past, becomes a bit more comfortable with it all, while strictly adhering to Mind over Manners... and then Sinister and the Red Room happen to him, torturing him and transforming his Blank Slate body into a killing machine akin to the Winter Soldier with superpowers. When he gets his body back, he unsurprisingly snaps, and it's far worse than anyone feared. A Roaring Rampage of Revenge takes him to the very edge of tipping over into the dark side of this trope. Specifically, by becoming The Dark Phoenix. He is barely talked down in time, and entire pantheons live in fear of what'll happen if he snaps again.
    • Magneto, naturally, is referenced, with Wanda mentioning that she called him out for it and that he wasn't particularly pleased. However, it seems to have sunk in, since he's mellowed by the time of the story's writing, limiting his antics to occasional cases of Pay Evil unto Evil. Of course, the monsters are still terrified of him, and for damn good reason.
    • Dumbledore also goes out to avert this, avoiding seeking power on the grounds that he's perfectly aware that he could become a Dark Lord who would make Voldemort look like a fluffy bunny, in large part because of his deep frustration with the insularity of the British Wizarding World.
    • The trope is also referenced in respect to Peter Wisdom a.k.a. Regulus Black, who is ruthless, manipulative and downright vicious in terms of how he deals with supernatural evil and in acquiring allies to do so with, stopping at nothing to achieve his aim, even - especially - considering his own life meaningless, reckoning that he should have died a long time ago and that anything after that is a bonus. At one point, Sean Cassidy, not an easily shocked man, takes a step back after looking in his eyes and seeing 'a man who had gazed into the void and made damn sure that it had blinked first.' Those who first meet him think he's very like his mentor, Nick Fury. Those who know him for longer realise that this is true, but all the knobs are dialled Up to Eleven. Fury has limits. Wisdom doesn't. He has the tattered remnants of a conscience, but it won't stop him from doing... anything, really.
    • Doctor Strange regretfully remarks in Ghosts of the Past that in fighting monsters and manipulating history and people alike to craft what he deems to be the best timeline - specifically, the one most likely to survive the coming of Thanos - he has become something of a monster himself.
  • In The Crow: Phoenix Rising it's lampshaded that Harry (as the Crow's avatar) has become a monster that's just as bad if not worse than the Death Eaters he's fighting.
  • DOOM: Repercussions of Evil
    "No! I must kill the demons" he shouted. The radio said "No, John. You are the demons". And then John was a zombie.
  • The Dee-Dee Morgendorffer (Daria's school nickname) of the long-running Daria shared-world series The Hallowed Halls Of Fielding fits this trope like a glove. In a world of horrible students, an administration and parents that make looking in the other direction a honored tradition and corruption of everyone in the manner of a virus, Daria (a middle-class girl there because of her grandmother's footing the bill) decides that she's not happy with the way things are (even though the system's been working for a couple of hundred years). In the space of two years, she's caused a few disruptions so severe that they've literally changed the face of the school (and the society they service forever)...
  • Harry Potter and the Methods of Rationality plays with this trope. As early as the Sorting Hat, people have known that Harry could be a terrible force for evil if he turned. Dumbledore even considers an alternate interpretation of the prophecy, that the Dark Lord shall mark him as his equal, to be that Harry will become his successor. Meanwhile, Quirell himself seems to be actively attempting to use this trope on Harry. Even Harry is worried about it, given how far he's strayed to the Slytherin side of things since the beginning of the story, and how he refers to Hermione, Neville, and McGonagall as his consciences. However, while he fights with Slytherin tactics, and even declares early on his desire to become a god and rule the world, he and Voldemort have very deeply different goals, and Harry is disgusted by the level of cruelty displayed by Voldemort, and has never once displayed the same cruelty.
    • It's implied that this trope happened to Dumbledore and while he never became Voldemort, and still doesn't understand why Voldemort did the things he did, fighting Grindlewald brought him so close to the abyss that fighting Voldemort made him break several rules and do many things he regretted.
  • Not only the theme but the name of He Who Fights Monsters, a Rosario + Vampire story where Tsukune never meets Moka or the others. To keep anyone from finding out that he's human (and thus stay alive), he's eaten bugs, made several Improvised Weapons, and killed 5 students, including Inner Moka. "When your life's on the line, there's nothing that you won't do to survive."
  • The Immortal Game: After Twilight Sparkle is freed from Nihilus' control and her mind splits in two, she , or rather, her dominant personality, Sparkle, becomes an Actual Pacifist, as she fears that this trope will come into play — she was forced to watch Nihilus perform countless acts of violence and torture For the Evulz, and is afraid that if she starts fighting those responsible for her transformation, she'll start enjoying it. When Titan's torture causes her mind to fuse back together, she realizes she was being foolish — she is nothing like Nihilus, and she will never let herself sink so low. Cue asskicking.
  • A fanfiction rewriting the 372nd chapter of Fairy Tail, Erza ends up in this path, though she still calls herself an innocent victim and calls Kyouka the true villain, as she tortures her.
  • In Low Light L realizes he's become this when he kills Misa with the Death Note.
  • Kingdom Hearts 4: New Light: Patria seems to be approaching this territory. There have been mentions of her having mass amounts of inner darkness, along with her suggestion to use a Jack Bauer Interrogation Technique, and her Hair-Trigger Temper and preference for violence as a solution. On top of it all, both Diaval and Pith, the latter her own brother, have declared her to be Not So Different from Maleficent.
  • MLP Next Generation: Know Fear!: It's been noted both in-universe and out that the more Starburst uses her Fear ring, the more she becomes like the griffons she's fighting. Which she comes to realize herself when Emperor Stratus gives her a Not So Different speech when she's about to kill him in cold blood. She decides she's better than this and doesn't kill him... at which point Nox/Shadow Wing does, in order to make Stratus a martyr and to frame Star.
  • Discussed and rejected in Parting Words. Celestia finds it ridiculous that people can believe standing up to bullies would make one as bad as them.
  • The Pony POV Series has the Mane Six in one of the alternate universes seen in the Gate of Truth. In this universe, they've become Knight Templar dictators of the world using the Elements to 'correct' anyone they see as disharmonic. It gets so bad Cadence goes Nightmare as a last resort to stop them.
  • Discussed in RainbowDoubleDash's Lunaverse. Luna doesn't dare take drastic action to curb the rampancy of the Night Court out of fear that she will become a tyrant little better than them. Trixie calls her out on her Fatal Flaw of irrational fear At the Grand Galloping Gala, being told that You Are Better Than You Think You Are and that the willingness to Do What Has To Be Done would in no way make her a monster. On the other hand, Trixie's willingness to put action to word resulted in a Broken Base, with some readers thinking that she has become as lawbreaking as the nobles.
    • This is also what caused Celestia to become Corona. She grew so obsessed with trying to protect her little ponies from all the dangers around them that she tried to control every aspect of their lives, becoming the Tyrant Sun. In the end, Luna had to use the Elements to banish her to the sun.
  • In The Hobbit fanfic The Monstrous Company of Thorin Oakenshield, Thorin set out to create a society better than the patriarchal one the Company, who are all female in this fanfic, have fled from. Some readers have commented that Thorin is rather close to becoming the monster, as males are only allowed into reconquered Erebor if they agree to be followed by armed (female) guards all the time. As of 2016 the fanfic is not yet completed, so it remains to be seen whether this will lead to becoming a monster, or stop at some point.
  • In Respect, this happens to Yayoi Kise. She makes a contract with Kyubey to stop bullies from tormenting her... and ends as a berserk supervillain, responsible for turning her home into a Ghost Town.
  • Anna Dollerious in an installment of The Secret Life of Dolls, which was named after the trope itself.
  • Rosario Vampire: Brightest Darkness:
    • In Act I, Astreal dips into this territory when she decides to brainwash Rason and Dark to force them to fight Ghaldin for her and Apoch. When Apoch points out that they'd be stooping to Ghaldin's level by doing so, Astreal insists that it's not the same because Ghaldin used the two of them to kill whenever and whoever he wanted, while they won't use the boys for such actions.
    • In Act VI, Talon is dipping into this territory quite well. The members of Fairy Tale who were actually responsible for his transformation are already dead, but he doesn't care; as far as he's concerned, everyone who was ever a member of Fairy Tale, including Unwitting Pawns and those who left willingly, is equally guilty, even Dark, who was one of the heroes who took down Alucard. In Act VI chapter 35, Akua and Kahlua even flat-out tell him to his face that he's no better than those who made him what he is.
  • This trope is a central theme of Sonic X: Dark Chaos. Most of Cosmo's Character Development revolves around her struggle not to give in to her sorrow and anger over her Dark and Troubled Past and hatred of Tsali. Jesus Christ himself muses several times about how the Angels have become just as bad as the Demons they rebelled against. Most notably, Dark Oak and the Metarex as a whole are pretty much this trope taken Up to Eleven until Dark Oak's My God, What Have I Done? moment.
  • Summer Days And Evening Flames: Sergeant Shared Justice, or "Sherry". Initially only a bit overzealous when it came to Red Hooves' crime syndicate, due to losing her husband to Red Hooves and watching him get out by LoopholeAbuse, but eventually turns as bad as the criminals she was hoping to weed out from Farrington. She initiates a gang war that gets dozens of her fellows police officers killed in an attempt to kill Red Hooves, shows no remorse when confronted, and ends the story with threatening to kill her former captain Iron Bulwark (who considered her a mother figure) and vowing to become the head-honcho of the Salliongrad Mafia.
  • As the title would suggest, this is a major theme in Those Who Fight Monsters.
  • At the end of White Devil of the Moon, it's implied that Luna might take this path after Nanoha decides to not resume her past duties as Princess Serenity and revive the Moon Kingdom.
  • Harry Potter in Rise of the Wizards after defeating Voldemort and coming to power he decides its time to have his revenge against the muggle world. "Magic is Might."
  • Super Mario: Dark Side: After the defeat of the Shadow Queen, Princess Peach began to have haunting dreams about herself taking over the Mushroom Kingdom, followed by a dark feeling that's slowly consuming her, given the fact that being possessed by an ancient demon gave her a traumatic experience. Adopting a With Us or Against Us mentality against her allies, she begins to impose dictatorial and extremist measures, conquers neighboring kingdoms, going so far to brainwash her subjects to form an army and use it to attack Bowser, and her cousin Princess Daisy, the ruler of the Sarasa Kingdom. And after gaining full control over the Mushroom Kingdom, she proclaims herself as Empress Peach, complete with a dress and stilettos similar to the one she wore as Shadow Queen Peach, effectively becoming a Manipulative Bitch and stone-cold tyrant, besides becoming the Big Bad of the fanfic. It's actually revealed that Peach was the reincarnation of Empress Deasalva Lumineska, the original Queen of Darkness who plunged the Mushroom Kingdom into evil before being defeated by Link and Zelda's ancestors. Peach's past self was corrupting her mind to commit such atrocities, going so far to have her seize control of the Tri-Force, becoming even more powerful. But after Peach defeats her, Deas turns to normal and has a Heel Realization where she regretted her past actions, and earns Redemption Equals Death, but not before redeeming Peach in front of her people.
  • Light Yagami (the innocent amnesiac version) in The Better to Kill You With, My Dear begins with high ideals and moral principals but he slowly begins Jumping Off the Slippery Slope once again after L's kidnapping and it gets worse when they retrieve L only to find what Beyond has done to him. In his despair and desperation he changes his mind about making use of Watari's "enhanced interrogation techniques." This coupled with his growing obsession and codependence on L is slowly turning him into a monster even more twisted than Kira ever was.
  • In a Digimon fan fiction Zero 2: Crisis on Infinite Digiworlds, one of the universe Davis travelled is a world where Kari is the only Digidestined left after taking down Davis's corrupt self Darkheart along with the absorbed Digidestined. Believing that darkness is evil and light is good, Kari began to systematically build hi-tokyo upon the old Tokyo, create a world where every single aspect of the people's life is controlled by the Queen of Light, unable to control any aspect of life, and completely seal any access to the Digital World in hopes to create a utopia where darkness and war will never happen. Unfortunately, this ended up completely stripping off humanity any of their free will, and judging from how her response when the old Tokyo is filled with Digimons hiding people that have not been purified be her light is to immediately purge them, this universe of Kari has become no better than the darkness she tries to extinguish and Azulongmon's claims that even light can corrupt is not exactly wrong.
  • In Kill Or Be Killed, the story begins with Leeteuk's death, with him serving as The Lost Lenore for Taeyeon. However, she becomes so hellbent on avenging her lover's death that she loses her sense of self to the point where she has to be killed to be stopped before she can become a big threat. Later in the story, Sunny's lover Sungmin is killed in front of her, and Sunny is so devastated that she almost commits suicide due to having nothing to live for. Her wants of avenging Sungmin's death almost turn her into a second Taeyeon to the point where, before dying, Yoona asks Yesung to tell her not to go down that road.
  • An aversion in Nosflutteratu's Garlic Flank Stake, who appears at first to be the typical "all vampires are evil and must die" vampire hunter but quickly changes her tune when she learns the vampire in question is Fluttershy.
  • The Open Door: To defeat the C'tan and Necrons, who plan to destroy all other life in the galaxy, NewChaos become The Unfettered and do some very questionable things.
  • Mortal Kombat: Desperation takes place after Shinnok's defeat at the end of Mortal Kombat X. The prologue references the Nietzsche quote, and is a central theme in this fanfic's plot. After he Came Back Wrong, Raiden is so blinded by rage and vengeance that he becomes just as cold-blooded and homicidal as Shinnok and Shao Kahn, to the point of alienating his ex-allies and refusing to reconsider his invasion of Outworld. Ordering the destruction of Li Mei's village (women, children and elderly included) places him into evil territory for good.
  • Fade: With his own Death Note and (incomplete) knowledge of events, L seeks to stop Kira by any means necessary. By the story's midpoint, L has effectively become the Kira he sought to stop. Light, meanwhile, subverts this — while still a Serial Killer, he is nowhere near as bad as L.
  • A distinct worry for Suzume in Eroninja is that Naruto might not actually be a Corrupter and that she's simply jumping at shadows in her plan to expose and murder him. Her biggest moment of doubt comes when she strips naked and (not really) drukenly begs him to fuck her. Not only does Naruto turn Suzume down and cover her up, but the next day he seems even more mortified than she does.
