Weirdest Fanfiction Ideas That You've Ever Had

Well, the title pretty much says the idea of this thread. What are the crackiest, strangest, or just flat out oddest fanfiction ideas that you've had (but not necessarily have written)?

I've said already that most of my fanfics are a bit of a Widget Series, but I have my limits. One scrapped idea I've had was one where some characters swapped bodies with only certain body parts of another character (someone switching with a leg, someone switching with an arm, etc.) and hilarity ensuing. (Incidentally, the character at the center of the plot was Lugia.)

Maybe I could have made it work (but probably only if I just made it a weird nightmare. Kablammin45Fanon!Lugia has a lot of them already.), but I honestly don't have a clue what I was on when I came up with a bizarre story idea like that one.^note  I should point out that I don't drink or do drugs. I was probably half-asleep or on a sugar rush when I dreamed that idea up.

An Alternate Universe fic where Darth Vader is an ace podracer that likes to challenge people to race in the Death Star trench.

You can thank our ''Star Wars'' thread for that one.

The weirdest part is I think this is a legitimately fun idea that could make for a great fic if injected with just the right amount of absurdity.

In lieu of IV fluids, Brook receiving milk intraosseously. Basically trying to rationalize One Piece medicine in general. Also, wondering whether or not Shanks can open a jar of pickles (or tie his shoes, before realizing he wore sandles).

Both ended up in one shots.

I just wrote a Neko Atsume fanfic based on a "lost at sea" story, because I saw two cats on a blue sled and thought it looked like they were on a life raft.

I also wrote a needlessly detailed NSFW Spongebob story a few years ago, I actually went to a (now very much nuked) thread in Yack Fest and got permission to insert some tropers. It was a good laugh.

Miguel O'Hara finds his universe making less and less sense - in the "the fabric of reality itself is unraveling" kind of way, not the "Go Mad from the Revelation due to assorted social bullshit" kind of way (that's kind of normal for him) - and part-accidentally-part-necessarily ends up accumulating a harem (including, his fiancée Dana and a time-displaced Gwen Stacy, among others) in order to gain the additional tantric power needed to defeat the CEO of Alchemax who in this story is an alternate-timeline Peter Parker who tried going the Ozymandias route and then somehow wound up taking several levels in Raoh over the past several decades.

Cut to the massively climactic final battle complete with epically cheesy comic-type-lines ("Amazing. Spectacular. Sensational. Once upon a time, you were all of these things and more. But.... your time came and went, twencen! I'm the Spider-Man around here now. The Spider-Man of the future! THE SPIDER-MAN OF 2099!"), Miguel triumphs over his foe only to be given one final, ominously cryptic message ("Finally, Miguel... your training is complete. Now you're ready for the true threat.")....

...

....and then Deadpool suddenly wakes up, vows never to read shitty Nasuverse-x-Megaten crossovers before bedtime anymore, and then promptly sets to doing naughty things with his smokin' hot succubus wife◊.

I'm thinking heavily about whether or not I should commit pen to paper on this one...

Changing the Kokiri from The Legend Of Zelda into bloodthirsty, cannibalistic, ethereal winged, wound regenerating, assassins in service to the primary villain. That was quite the interesting turn around for those characters.

This Zelda darkfic writer says that sounds creepy-awesome.

I actually *write* most of the weirdest ideas that I have. I mean, it seems like the weirder it is, the more likely it is to get written.

Some ideas that are stalled / not quite written yet that are a bit strange:

I wrote the first chapter of something I called "Attack on Trophy." It's up on the fanfiction network and is a fusion of Super Smash Bros and Attack On Titan - the premise being that the giant versions of the Smashers you get to fight on some stages are mindless clone-copies of the real, small size characters and they got out of their holding-area and went all Titan on the Smash-verse. I never wrote further than that first intro chapter, but I have ideas for the stupid damn thing - actually... very tragic and dramatic ideas for the stupid damn thing.

I have an idea, courtesy of my man who enjoys watching me play Hyrule Warriors for a story in my already purposefully weird and mostly comedic series of short fics "The Madness of War" involving Link waking up in Cia's chambers next to a big body-pillow with a print of his own image on it.

My guy and I once had an idea together for if we ever get into doing AM Vs to do one of Mr. Krabs from Sponge Bob Squarepants to Bon Jovi's "Dead or Alive" (which you will understand if you've ever watched Deadliest Catch ).

I just remembered another bizarre idea I had, but unlike the other one I mentioned, I actually wrote it some.

Inspired by some drawings I made of Samus mistaking a pterodactyl-like original character of mine for Ridley, I started a story which seemingly just started off with a typical Freaky Friday plot between said OC and Ridley, but wound up escalating into a bizarre crossover story where it turned out that a malfunctioning ice cream machine made by a pair of bumbling inventors was behind the "Freaky Friday" Flip...and a billion other strange things that had happened across time and space, and things were getting weirder as time went on. Among other weird things in this bizarre universe:

• The settings of Super Mario Bros., Metroid, and The Jetsons had fused together. Bowser (or, rather, "Bowley") was now the princess, and the Mario Bros were now Fred Flintstone and George Jetson. (I didn't get far enough before I stopped actively working on the story, but the princess kidnapper was intended to be a gender-flipped Egomaniac Hunter version of Peach.)
• Samus (who remembers the "normal" world) is told that she is just a Mexican-food vendor who drives a food-truck. (She is not happy about this.)
• A chunk of people in a town have been transformed into pink flamingos.
• And it's mentioned that The Proud Family was exposed to the atmosphere of a strange planet inhabited by giant mutant animals, turning them into a crime-fighting crew capable of morphing into said giant mutant animals.

Crazy, huh?

It's been a while since I've worked on that story, but I kinda feel like working on it now. I don't feel like the story (at least what I've wrote of it) is terrible despite the bizarre premise.

A Flash (TV series) AU where instead of Ronald Raymond and Martin Stein being Firestorm, it's Ronnie's fiance and Martin's wife—but the canon villains etc still think Martin's the mental half rather than Clarissa.

Also a Young Justice AU where Dr. Fate doesn't release Zatanna as his host...up until he realizes that he really doesn't want to deal with 40 years of periods.

An Evangelion AU set in the universe of the first edition of Vampire The Masquerade, where Shinji Ikari is a Malkavian vampire.

I have this weird idea for a very crack on steroids Death Note fic. No idea what was I thinking, but well, anyway. this is the idea.

L finally feels like he is having real progress on the investigation, he is 100% sure he has got the second Kira and it is only a matter of time before she cracks and starts not only confessing her own crimes, but how does she do it and that Light is indeed Kira.

Then he receives a call from Light, he tells him he wants to talk. Later that afternoon he comes and tells him he would want to talk in private, without the taskforce. L conceedes. Then Light begins rambling on how important his mission is, and how his actions while illegal are only for justice. Then he goes how he found a notebook, a special notebook, one that came with great power that changed his life forever and saddled him with a mischievous magical roommate with an addiction to apples.

He then shows him a black notebook, it looks like an ordinary notebook. Until one writes a name, speciffically his own name. Then things start to take a turn for the weird. Light writes his name and gets surrounded by a bright light as the notebook glows gold turning into a magical girl all the way with a kero expy in the form of an apple worm. Then Light the magical girl shrinks L, carries him around and jumps out of the window to fight the forces of evil in a psychedelic acid trip of magical powers, magical ponies that turn into mechas, double-double-triple-reverse double crosses and a high stakes game of children children card games for the fate of the world that somehow devolves into a mini game of crazy bones, strip crazy bones...

After the dust settles L is so sick of it all that just decides to let Light go, but the worm-kero insists on erasing his memory of the events, but upon realizing that without the memories of the event he would go back to pursuing Light and then unavoidably back into the cucko carousel he decides to tell his name as a collateral, just so he can try to forget the whole thing and move on.

Later on he just binges on kit kats as a way of self therapy, until the chokes and dies... just as planned by Light, who staged the whole thing to get his name and just used the deathnote on him. Then as he celebrates with Ryuk and the Worm-kero he has a fit of hysterical laughter that causes him to suffocate. Then notKero asks Ryuk if he knew that was going to happen and both decide to look for a new victim and settle on Keitaro -yes that Keitaro-

I once wrote a short novel called Hanks Raccoon Plantation, which was basically Apocalypse Now with evil raccoons instead of Vietcong.

That actually sounds awesome. I'd read that.

Anyway, I didn't have a weird idea for a fanfic so much as I had a weird idea for an OC... or rather, one that's weird outside of its series. You know how the Metal Gear games are well-known for, amongst many other things, Quirky Miniboss Squads consisting of SpecOps troopers with bizarre superpowers? Well, the other day, I think I challenged myself to make one that was even weirder than The Pain.

The character I came up with was a fellow simply known as Shepherd (no, not that one, and certainly not that one). He's a former ANZAC commando that, after a botched experiment involving potential Psychic Powers and gene splicing, picked up the ability to command Sheep. His mandatory boss fight against Snake (Solid or Naked, you decide; I was more inspired by Snake Eater with this one) had him hiding inside a giant herd of Sheep that would gore Snake to death if he got anywhere near them, forcing him to stay on raised ground or behind cover. Snake would have to track Shepherd by keeping an eye on the literal Black Sheep in the herd and firing in the air to get them to spread, until he'd eventually force Shepherd to leap out and try to shoot him in the face with a Sawed-Off Shotgun, whereupon Snake would have to time a CQC counterattack to tackle him to the ground.

After taking some damage, Shepherd would mix things up by ASSUMING DIRECT CONTROL of Super-Persistent Predator Rams that bypass cover and can deflect bullets with their horns. And the whole time he'd be spouting off Sheep-themed puns, like "It's baaaaaaaa-d news for you, Snake!", "I wouldn't want to pull the wool over your eyes!", "This'll shear your pride!", etc.

Oh, and the obligatory Tear Jerker cutscene after he's defeated would reveal that a side-effect of the aforementioned experiment was slowly transforming him into a Sheep, thus explaining his wooly hair and Sheep-like left eye. And then his now-friendly herd would drag his dying body away, only for him to show up again later, having survived and fully transformed.

It's not the only idea I've had for a Metal Gear boss, but I think it stands out as the weirdest of the bunch. Damn, writing this description has made me want to draw the guy or something.

Gurren Lagann as a Free-Love Future.

...

...yeah, you can probably guess why I'm not elaborating on that.

Eh, I've had weirder.

Such as taking the Universal-Adaptor Cast of Lyrical Nanoha, putting 'em in a Professional Wrestling context (and completely averting the Professional Wrestling Is Real trope, such that most of the action is basically therefore a Show Within a Show), and then that being somewhat less than worksafe.

Did I ever tell anyone that I wrote a story where the mane six flew inside a fabrige egg spaceship to other worlds on a quest to save someone's life?

I was *this* close to making it work, too. But it was terrible.

I once had an idea about Asuka getting her degree from [[Series/Community Greendale]] with her actually being part of the Study Group when she was there.

I had an idea, to make a sort of parody of bizarre ships, which was Flowey x Papyrus. And i actually realised this one, it's on fanfiction.net, it's called "The Floweying", and was intended as Troll/Crack/Bizarro Fiction inspired by "Until the end of time".

Well........

Rhaegar Targaryen turning Oberyen Martell into his personal sex slave. It was disgusting, I WOKE UP!

Metal Gear Rising: Revengeance except starring Luigi. With Waluigi as Jetstream Sam, a mechanical Yoshi as Blade Wolf, E. Gadd as Doktor, Lanky Kong as Monsoon, and Toadsworth as Senator Armstrong.

And throwing Mecha-Bowser into the air by swinging it by the tail while Rules of Nature plays.

I never actually wrote it because it'd just be "the same story but with character substitutions", and I couldn't figure out who to sub in for Mistral, Khamsin, or the rest of the Codec folk.

A Dresden Files/The F Lash 2014 crossover set in the timeline created by the end of Season 2, aka, 'Flashpoint-Lite'. Because Barry's mom never dies and he imprisons the Reverse Flash, Harrison Wells and his wife never get killed. They start up STAR labs as they should, then sell the Central City sight to Cisco Ramone as the HQ of his company while they move to Chicago to try out their Particle Accelerator. It explodes on the night when Harry Dresden hs a date with Susan and the Shadow Man sends a demon after them. In fact, it happens just as he's tapping a lightning bolt from a storm that's happening to fry the demon... and gets knocked into a coma.

While he's unconscious, Morgan finds and kills Victor Sells, since his prime suspect isn't waking up but someone still got killed. He wakes up months later in time to use his newfound superspeed to survive the loup garou...

One of the weirdest ideas I have is where a bunch of Gjallarhorn ships somehow get stuck in a dimensional rift and end up orbiting a planet covered almost entirely in water. After sending down a scouting party, it isn't that long before they realise they are on Earth... just a different one, in fact. Realising that it's not so easy to figure out how to get back to their Earth, they eventually settle into the role of Gargantia's newly-outsourced police force and defence fleet. A rivalry between the MC Mobile Suit Pilot and Ledo forms, Chamber may be restored as a Mobile Suit, all sorts of adventure are had...

And then the Galactic Alliance show up. I was kinda inspired by how the Hideauze and Galactic Alliance were compared to the Zerg and Protoss respectively somewhere, so I figured that the Gargantians could have used a sort-of beef-up and what better Terran-esque beef up than Gjallarhorn? They use bullets and their MO is giant robots, like a lot of the Terran units. Why the hell not?

Oh, yeah, and did I mention that Gurren Lagann was gonna be involved somehow?

I'm actually currently writing/trying to think of ideas for a series of stories involving magic artifacts and gadgets that fall into the hands of...the Finding Nemo/Dory crew. I've kicked around ideas with them interacting with the artifacts and gadgets that involve plots that range from run of the mill (i.e. several characters experiencing a "Freaky Friday" Flip, Dory (and Hank) being turned into infants, etc.) to just downright insane (some of the characters becoming magical girls). There is an overall story arc involving dimension-hopping pirates trying to get back said trinkets (as they were the ones who originally found and lost them in the first place), so it's not just complete silliness/crackiness.

All extremely stupid ideas, I know, but I wonder if I could make it work....

I've had a few ideas for various Zootopia fanfics, most of which never actually get written. I'm not sure if it's as weird as some of these other ideas I've seen here, but my most recent one wasn't so much a story as it was a piece of in-universe journalism. Gonzo-style journalism, to be precise, written by a Hunter S. Thompson expy called Sonny Vicentina (who's a sheep, obviously :V), who takes it upon himself to investigate the excesses of Night Howler culture once derivatives of it began to pop up all over the place, becoming the next big recreational drug^note For those who don't get it, it's become something of a Fandom-Specific Plot for Night Howlers to resurface as recreational drugs after the events of the movie, usually in modified forms; but it seems to me that a lot of the time, they're used as simple plot devices rather than exploring their effects more in-depth like. Which isn't a bad thing, mind you; one of my favourite fics and both the ones I'm writing do exactly that.. And he does this by bribing his way into fucked-up parties, getting stoned off his woolly arse, and getting accosted by addicts, Mafiya goons, crazy nastyass honey badgers, and possibly Gazelle's agent. But it's all good, because he has a lawyer with him.

Obviously it'd have to be in first-person (it comes with the territory), which isn't something I'm good at, and I understand is hard to pull off without it coming off badly.

A while back, I think I had an idea for a possible (but sadly unwritten) Marble and Luxray fan comic series back when I was just renewing interest in Pokemon. It wouldn't have been dissimilar to something like Scooby-Doo and similar mystery-focused cartoons, if Scooby had X-ray vision. That in of itself isn't a weird idea, but one of the ideas I was running over in my head is apparently a crossover with Chowder (yeah, at the time Cartoon Network was still running both Pokemon and Chowder in the US). Apparently, Marble and her Luxray were to solve a mystery in the Chowder universe, perhaps in Mung Daal's Catering. Talk about trying to fit a square peg in a round hole.

Thankfully, nothing came out of this idea. I probably wouldn't have replicated Chowder's rather unique sense of humor well enough for it to work anyway, let alone mesh it well with the workings of the Pokemon anime (let alone one-time characters like Marble and her Luxray). The series idea itself isn't such a bad one, but I'm afraid that me handling such a concept would result in They Wasted a Perfectly Good Plot in my now-matured mind, so that series idea is still up for grabs, I guess.

As for the mystery of the Chowder crossover, I already forgot what I had in mind. Maybe a case of missing Burple Nurples, a Roast Most, the true meaning of Knishmas, mystery of the druids, whatever.
