Sandbox / Fanfic Ideas

Go To

Page under construction and in no way shape or form to be used as an index.

This is a page that lists ideas for Fanfiction, mainly ideas from people who don't have the confidence, the talent, the skills, the passion or willingness to put in the effort to just sit down and write it themselves. Not everyone is meant to write, but a good idea is still a good idea whether it is put into practice or not.

Please put what media-work the fanfic ideas are based off of. If you have any specific details about the story, characters or the medium, please include it into the description. Please refrain yourself from making edits to another person's idea, but if you have anything to add to a preexisting story idea, please indent the following example under the preexisting example. See Example Indentation in Trope Lists for context.

Compare with List of Shows That Need Summary, Fandom-Specific Plot and Fanfic. Not to be confused with Video Ideas.

    Fanworks 
Harry Potter and the Methods of Rationality
  • Harry and Hermione dedicate their second year using scientific principles and magic's latent abilities to create a wizarding equivalent of space-travel.

Nymph and the Corrupted Miraculous

  • In the canon!universe, Hawk Moth creates a space-time villain who conjuring up a portal to escape, but Cat Noir destroys the akumatized object mid-conjuring and ends up creating a rift in the universe, causing Ladybug be sucked into it. In the Nymph!universe, Lady Nymph creates a space-time hero functionally identical to Hawk Moth's villain to help fight Xue Ying's new team of miraculous villains. Xue Ying destroys the object housing the tianshi and it creates the other end of the rift, causing canon!Ladybug to fall through into the Nymph!universe. canon!Marinette marvels at the various minor differences between her world and this new one (including herself being in a wheelchair with Hawk Moth's powers, Chloe being nice and a lesbian, Adrien dressing in black instead of white and being this universe's Cat Noir, rationalizing that it is unlikely that her own Cat noir could also be Adrien) and asks the Miraculous Heroes of this new world to help her get back to her own world.
    • The same concept, but canon's entire Miraculous team is sent there instead of just Ladybug. Particular emphasis on canon!Chloe and Nymph!Chloe meeting, as whole Nymph!Chloe is genuinely a better person who grew out of being a Spoiled Brat, canon!Chloe will act as an interesting foil to in an "I Hate Past Me" way.

Powers of Invisibility

  • Juleka has been a member of Team Miraculous for nearly a year. When they fight The Collector, Juleka gets a bad feeling when they fight. While she ignores it at first, her "turtle sense" hits her like a truck when she meets Gabriel at the fashion show after defeating Style Queen, becoming incredibly suspicious of Gabriel. While she humors the idea that he could be Hawk Moth, she decides not to worry her team and do some personal investigating.
  • Juleka entrusts the Bee Miraculous to Rose and they become a Battle Couple.

How to Train Your Dragon
  • A Lemon drabble set before, during and after the events of the first film where Hiccup and Astrid are in a secret relationship where they only act like they do in the film (him having a crush on her and Astrid being aloof and unaware about it) in public. The various places they take the time to do it, the various close calls they have of being discovered and the notion that Gobber may or may not already know about it can be Played for Laughs, the fact that Hiccup has been keeping Toothless a secret from her and the very real threat that the village will discover what they have been doing can be Played for Drama.
  • A fluff AU fic where clothes are considered taboo on Berk and everyone there are cultural nudists.
  • Instead of trying to show Berk that dragons can be tamed when he should be slaying the Monstrous Nightmare, Hiccup instead sneaks into the Kill Ring the night before and frees all the dragons there when nobody is looking, buying him more time to come up with a better plan before the next raid.

Machete

Marvel Cinematic Universe

  • Instead of Peter Parker becoming Tony Stark's ward as a Science Hero and a mutate, a young Peter happens upon the Sanctum Sanctorum and winds up becoming Doctor Strange's apprentice in the art of mysticism instead. Later in his training, he develops spider-powers when he feels an innate attraction to a relic - a statue of Anansi - and is bitten by a spider housed within it, a reference to the origin story of Spider-Man: Noir.

    Literature 
Harry Potter
  • Harry is discovered to be a natural-born seer in his first year, having remarkably accurate dreams of future events (both in the immediate future and the far future) and will routinely hear and see things before they happen like a magical deja vu. The Dursleys believed that he was schizophrenic and would routinely beat him whenever it would act up, thinking that it would be preferable than having the neighbors know that they had a relative in the Mad House. Because of this, Harry does everything he can to keep this ability a secret when he attends Hogwarts.
  • Instead of the Death Eaters wanting Harry killed as revenge for the Dark Lord, they all wind up believing that Harry is destined to be the true Dark Lord when Voldemort falls trying to kill the infant Harry. They start behaving less like a terrorist group and more like a cult, having been trying to find him throughout his life and then try to kidnap him when he starts attending Hogwarts, wanting to make him their new Dark Messiah.
  • Harry Potter is a Child Prodigy when it comes to mechanics and coding, capable of creating advanced things like desktop computers and remote controlled doo-dads using out-of-date tech and everyday objects. When he gets his letter and is brought to Hogwarts, he makes it his goal to make technology that can function properly in wizarding areas. Over the years, he manages to use magic and technology to help bring Wizarding Society closer to the 20th/21st century, including: magic mirrors that receive television signals and can be used to play video games, microwaves, vacuum cleaners, electric stoves for cauldrons, electric heating systems, pocket pensieves that work like cellphones, electric ovens, etc.

  • A reboot of Michael's Good Place experiment where the "Good Place" is a place where you can literally buy your way into Heaven and everyone there are all uptight rich assholes who spend all of their time gloating about how the poor are all being tortured in the Bad Place.
  • A reboot of Michael's Good Place experiment where only Fascists could get into the Good Place and they are all separated into different blocked-off sections. Eleanor is in the White Supremacist section of the neighborhood, Chidi is in the African Ethnostate section, Jason is in the Philippine Falange section and Tahani is surrounded by Islamofascists. They all basically have to pretend to agree with those ideologies lest they all be found out, with a lot of the "activities" that Michael plans being based around encouraging superiority complexes and endorsing hate crimes before the walls separating the groups "accidentally" collapse, leading to all of the groups trying to genocide each other.

Once Upon a Time

  • Shortly after the Dark Curse was broken and magic was brought to Storybrooke, a series of gruesome murders begin occurring, with various corpses found in and out of their homes either violently disemboweled or drained of all of their blood. When Dr. Whale overhears the morgue doctors talking about, he recognizes the cause: there is a vampire running loose. Vampirism being a curse uniquely native to his world, Whale was able to follow the trail to the vampire. It turns out to be Count Dracula - an old friend of his that he had made in his research to perfect his procedure - who was nothing but a dried up corpse in the Storybrooke Cemetery until the magic returning brought him back to life (albeit as a blood-starved ghoul that was slowly regaining himself with every victim).

However, his rare abilities make him a prime target, including a certain King of Heroes who wants this rare human as his treasure.

He sees massive improvements in his life, but develops a phobia to his game collection because he worries it will make him regress to his old miserable self.
