#crossover fic ideas

[kitkatt0430]

Just imagining Barry, Kara, and Oliver hanging out in an alien bar. Oliver is the designated driver because Kara is getting Barry to try the alien alcohol to see if any of it affects him without the instant-drunk that Cisco & Caitlin's speedster alcohol achieved.

Just... Oliver hanging out with two tipsy sunshines while he's the sober one. Being won over by how adorable they are against his will. hehehe

Not Slugterra related sadly but I need some fics where we have a Young royals crossover with RWRB where Young Royals was months before RWRB started and the fic is where Henry and Alex meet Wilhelm. Alex being bilingual with Spanish and English he surprises everyone with knowing intermediate Swedish and with that all three of them have a conversation about, let’s just say a gala coming up, and the conversation moves to Wilhelm bringing a date, the older couple knowing Wilhelm they ask “who is the boy” and Wilhelm just goes “No boy, not anymore”

Que the couple being ConcernedTM

Yesterday I was going on the bus, watching the landscape pass as one does when bored. And then suddenly my brain started to play "I'm a girl like you" with the scenery and everything. But instead of being Anneliese and Erika, it was Danny Fenton and Jason Todd, and I don't know what to do with that.

It makes a bit of sense if it's Ghost King Danny or soon-to-be-ghost-king Danny who doesn't want to rule + Jason who is having his 727599th crisis for whatever reason. Maybe a LoA Jason who travels from here to there bc is running from Ra's and can't/doesn't want to go to Bruce for whatever reason (and that's valid).

Then they bump into each other and they are so confused. Why do they look like the other? Who knows. Maybe a clone, maybe lost brothers, maybe they aren't blood-related and it's just a doppelganger thing. Maybe it's the fault of the ghost zone.

Either way, they switch places to help the other. Danny gets a fun time leading the assassins into the most strange persecution any human had experienced. He keeps popping off and on suddenly and now the ninjas are afraid of him. Every time he wants a rest he just changes into Phantom and puts civilian clothes over his suit. People think he's just a meta doing tourism. It's like variations.

Jason ends up in a castle with a worried giant pink lady, a yeti, a floating blue baby, and a bunch of less outstanding but equally diverse ghosts. After presentations and explanations are exchanged, Jason gets his health checked by the yeti— which is unexpected but awesome— because he had been on the run for almost two months. He doesn't have any wounds, but he has a new existential crisis because he has a core wtf. The good thing is that his abilities now include ruling a whole dimension. It's way easier than he expected, maybe because they're ghosts (Pandora, who is his main tutor, says that he's just too used to things being hard and he just have talent). He's starting to feel better now, too. If it's a side effect of being in a safe place, the ghost medical care, his new friend Jazz's tendencies to therapy him, or a mix of everything, he isn't sure.

It scaled, but if you want to add anything do it or if someone write a fic with Jason and Danny switching places or singing barbie songs, please tell me.

Part one of crossover idea I had

Alright so on to that idea I had that I said I would explain in more depth that I do not have a name for yet because I am not that creative with names.

Though knowing me I’m going to get too into it as I do this and make more problems for me.

Oh well.

Anyway~

So the main driving point of this idea is that Lloyd has two half siblings from other worlds in Lucy heartfilia from fairytail, and Neil from Class of the Titans (if you don’t know this one I recommend it’s great)

How does this work? Well we already know wu and garmadon got up into shenanigans in their thousands years of life as demigods so you can’t tell me they didn’t go to other worlds a lot when they were young.

So on two occasions, garmadon had sweet but short relationships with women before leaving again, and those women found other partners they married. They assumed the child they had came from them, not the stranger of their brief relationship.

You can imagine, for at least the heartfilias, the surprise when the other genetics kick in

Look garmadon is a demigod dragon/oni hybrid you cannot tell me his genetics won’t be weird

I mean look at Lloyd he received most of the oni genetics and the elemental power.

Agh I’m getting off track ANYWAY

Lucy is the oldest child, Neil the middle and Lloyd the youngest. The biggest age gap is between Lloyd and both his siblings. Neil is maybe four or five years younger than Lucy. And Lloyd is 12 years younger than Lucy.

Now back to the other stuff

Lucy received a lot of dragon genetics from garmadon. You can imagine what happy little terror she was. Some of her genetics are physical attributes such as her teeth being sharper than normal or her bones being denser. She gave her parents so many heart attacks.

I also want to develop how this also effects her celestial summoning and celestial magic in general.

I’m going to take so many liberties with it but I’ll save that for another time

Neil is mostly human, his Greek heritage and power of luck aside he’s the one who has almost entirely skipped out in the oni and dragon genetics and the instincts that come with them (I bet it’s the luck) though he also has some uncharacteristicly sharp teeth when he gets angry.

He doesn’t have to deal with nearly the same amount of drama or chaos as the other two do, so he’s really chill. Even later when the Cronus thing is going on. He’s so used to the bullshit his siblings deal with that it does not phase him at all.

Now Lloyd of course got the brunt of the oni genetics, though he’s not at the stage where he can access his second form. It effects his behavior in a lot of ways that I’ll probably go into later.

Now onto the other part.

Lucy and Neil meet first. Lucy when she wants to escape her dad’s sad and depressing and psychologically abusive home environment and the fate her dad wants to force her into, subconsciously uses her magic to send herself to the closest relative

This sends her straight to another world and through the roof of Neil’s house.

His parents are chill with it, and Neil’s mom vaguely recalls a handsome stranger doing the same thing at some point.

Explaining her situation and what happened (his parents are used to this and the Greek bullshit of their lives this is nothing) they quickly realize that the stranger is Neil’s and Lucy’s dad. But they can’t just let her return to a dangerous environment (in their world Jude would have been imprisoned for child abuse/neglect and attempted child marriage and trafficking) and decide to keep her there with them.

It’s a much better environment for her and it takes a long time for her to feel comfortable with therapy and the calm attitude of the home.

She and Neil get along great and are similar in many aspects. There are many shopping sprees and late night gossip meetings with snacks, nail painting, face masks and romcoms in the background

They also found out the hard way that they both have latent luck abilities, and that when they are together that luck cancels out so it’s just normal luck. As seen when Neil was doing something he normally would and then was suddenly injured when that has never happened before.

Lucy eventually leaves to travel her own world and join the guild of her dreams. (I won’t go into it here but her dragon instincts really get into it with the other slayers and erza)

Also the seven year time prison thing doesn’t happen and instead it’s like 3 months

A few years later, a few guild wars and an actual war happened, Lucy unlocked her full dragon form and rocked acnologia’s shit and killed him. And Neil’s been chosen by the gods of his world to kill their dad/relative of chaos.

At this point the traveling to other worlds is figured out, and Lucy would rather Neil come to her so she doesn’t cancel out his luck if a surprise attack occurs and he’ll need it.

She’s a free mentor to the team and as she’s a person who’s killed a chaos being her insight is extremely helpful

Neil and Lucy decide they want to meet their birth father and decide to use the same spell Lucy did the first time to find him.

Instead they found themselves in a frozen cold region with no one for miles around

And a small fragile 8 year old Lloyd who is the only one around.

They immediately know he’s a sibling and are absolutely furious at whoever abandoned him out here by himself. Their dad forgotten.

Lloyd is hesitant to trust them but his instincts recognize them as elders in the family so he goes with them. They learn that their shared dad is in the underworld and that Lloyd was supposed to be with his mom or uncle and away from their dad, as garmadon feared he would hurt Lloyd in anyway and wanted him safe and away from him. Learning their bio dad isn’t at fault was nice but they are still angry about the abandonment and obvious neglect and possibly abuse from the boarding school on Lloyd’s behalf (if it’s burned to the ground and all the children being out in better places with actual proper therapy and help for their psychological issues and neurological disorders and teachers arrested then no one needs to know)

For a lot of the time he’s set up with Neil’s parents or Lucy and the guild. They all adore him and are angry on his behalf.

Lucy is completely furious when she bonds with Lloyd and knows his story is considerably mirroring her own and sends her spiraling.

Neil is angry on both of his siblings behalf’s and will be endlessly petty. Lloyd spends a year happy and fully integrated into the family.

Then they hear new that garmadon was defeated by ninjas.

They of course have to see it for themselves and travel to the underworld and finally meet him.

He knew about Lloyd, but now he’s completely blind sighted by two other children he didn’t know about.

Surprised and horrified that there were two other children of his he didn’t get to know or love or be worried about.

They’re there now though, and now he has two other spaces in his heart to keep his sanity.

Honestly I could keep going but I really need to stop or this will go one forever. I’ll pick this up again later

for me, the main draw of a young avengers/champions/younger marvel heroes (they go in the same circles and have crossovers) and a Young Justice Animated Series crossover is the interactions between Speed and Kid Flash. Very specifically these two characters.

Think of the drama. The angst. The parallels. Tommy landing in the YJ universe for no reason, and having to deal with losing the little stability he'd scrounged up for himself. Wally being insecure about him being faster than him, too. Their conflicting opinions on being 'legacy' heroes. And their takes on keeping secret identities. It's got so much potential.

Well… I’m going to need to figure out a way to get my mail to run normally on the iPad.

I found my notes for the last chapter I needed to write for an old Greatest American Hero/MASK cross over … and notes for its sequel.

I also found my Tracy’s on the Lexington story, but I’m leaning on changing the Hood subplot and maybe getting Fischler the bad guy instead as I can make the serious aspect into an experiment gone wrong. It’d also explain why the Lexington gets moved….

But they’ve been fun to read again.

••••••••

Though why they have me dreaming of rescuing Dr. Bashir from a shuttlecraft invaded by the Founders creating floodwaters - in space (Deep Space Nine) and then turning Captain Scarlet into a Mommy Long Legs (Poppy Playtime) I’ll never know.

(Please don’t ask… it would’ve had some sense if I had Dusty with Backlash in MASK in the mix).

[marbelcrossovers]

Okay so this is really random but as a fellow lover of weird crossover ships I got to be honest I’m dying over here 😭 and I saw a Jason Todd post on here so I desperately need to know if you’ve ever thought about Jason Todd/Bakugou Katsuki because it’s all that’s been on my mind lately but there’s like a single random wattpad fic and nothing else 🥲 and then there’s only a handful of incomplete gen fics where they interact and even fewer without Bakugou faces consequences. I haven’t gotten obsessed with a pair this rare in ages so I need someone to either validate me or whack me in the brain until I forget about it entirely.

Haha ahh that was very overdramatic but any how I’d love to hear your thoughts(even if it’s just to say you can’t see it) because otherwise I’ll have to start writing for it and I really don’t need anymore wips 😅

WRITE FOR IT PLEASE!! I WOULD READ THAT CRAZINESS!! I've seen a fic with Jason x Shirou (from Fate) and Voldemort x Lin Daiyu (classic Chinese literature) so honestly, nothing weirds me out LOL. Go wild with all the crossover ships!! I'm not quite sure I'd want to put Katsuki through the DC mayhem though...there's already enough pain in canon. I just know he'd get targeted by Joker if he got involved with Jason and that seems too angsty and cruel for both Jason and Katsuki. And Jason would always (want to) go back to Gotham. His Gotham, with the batfam and all it's troubles, not a parallel Gotham or another world. So I don't see a happy ending for the two staying together. If we merge the two worlds on the other hand...LOL, I'm honestly surprised the world hasn't exploded yet.

Been thinking about a crossover between The Owl House, Invader Zim, Steven Universe, and Gravity Falls in the form of conspiracy nuts internet forum where Dipper Pines, Ronaldo Fry, Dib Membrane, and Jacob Hopkins all frequently post, with the firm belief that they are the only ones who actually know the truth and the rest are just sheeple with overactive imagination. I could imagine them being kind of internet friends, but at the same time also firmly believing that what the others claim to be true is not so and that only they have actually had any real contact with the paranormal.

And then the concept of these four existing in the same universe took over my mind.

Anyway, I’ve rotated the thought of cartoon conspiracy nuts in my head for a while now, with the sliding scale from Dipper Pines, who’s the good example, to Jacob Hopkins, who’s the bad example and how Dib Membrane and Ronaldo Fry kind of drop between these two in slightly different ways.

Dipper is basically just a nice kid who’s also into cryptids and paranormal and conspiracies, and while he spends nights scrolling through the boards and videos, he struggles with how much bigoted, dangerous garbage he has to pore through in his quest to feed his interest. But being insecure kid on the internet has taught him to not talk about his discomfort out loud, so trolls don’t get the chance to dogpile on him.

Jacob Hopkins meanwhile is deep in the incel, redpill, illuminati hole and has no intention of getting out, but he does have the presence of mind to mask his worst opinions, even on the internet. Sure, you can tell that he is on the edgier side of internet-humour, but as a veteran redditor he is very good at muddling the waters on how much of his bigotries are actually real and not just ironical, and therefore appearing as a much more reasonable and friendly guy than what he actually is to any lonely soul browsing the internet for comfort.

Dib Membrane as another, even more insecure kid, would fall for that act hook, line and sinker. What Dib in truth wants is to be more like Dipper, it’s just that in the world of internet forums he could never admit to something as sincere as that. Dipper is somebody with friends and a family who likes him, somebody with enough social skills to actually *make* friends, and Dib is jealous of that. Unfortunately, Dib’s habits and his view of the world falls much more in line with Jacob. For Dib strange things are potential enemies first and vivisecting a creature would be worth it if it means that Dib could prove himself right in front of the sceptical world. This means that while Dib would like to befriend Dipper, his bursts of hateful rhetoric about the world keep convincing Dipper to keep him at (virtual) arm’s length. Jacob on the other hand is always there to egg on his worst impulses.

Ronaldo Fry on the other hand is the opposite. He *wants* to be more like Jacob, or what he imagines Jacob to be like. Someone that people are slightly afraid of. Someone edgy and confident and a cool lone wolf. Ronaldo is fascinated by the worst parts of the internet conspiracy culture, but of course, in real life he is constantly being exposed to the essence of Steven Universe, so he has ended up being a pretty nice dude. Annoying and kind of pathetic yes, but the idea of long-time imprisoning or God-forbid vivisecting a living creature makes him squemish. Even when he tries to be an asshole lone-wolf, he can’t help but adhere to basic good manners and kindness. It helps that Steven’s three moms could and would destroy him if he ever crossed a line again after the sneople debacle. But over the internet Ronaldo has a bad habit of idolising Jacob while completely failing to impress him, as he just doesn’t have the imagination for the kind of hateful cruelty that actually interests Jacob. (While Dib absolutely has the imagination) Dipper thinks that Ronaldo is a much more cooler dude to chat with than the other two, and cannot wrap his mind around why Ronaldo would want to seek validation from Jacob so badly.

idk, I think there could be some really interesting dynamics even for a fic that would take place completely as private chats, but then if you made the characters actually move between cities…hmmm.

[notemily]

I would like you to know that every time you post about dream, for a full three seconds I’m imagining Morpheus and I am confused.

I'm convinced that someone needs to write a crossover where Dream meets Dream, but like, I'm afraid it'd have to be me 🙃

[linettefox]

Last one. I will be making one of these for each of my top fandoms till I have a character to represent each in a one shot fic.

[ghostbsuter]

He'd been flying above Metropolis.

Like a good ghost! Doing nothing but relax! Enjoying the weather, really.

It was so cool, Superman came up to him, they talked even! Superman was very, very, uncomfortable when Danny mentioned he was kinda dead.

It was really awesome.

Yeah, the keypoint being was.

Now? Now he is in Superman's arms, very much alive after being hit by a stray beam from Lex Luthors newest invention, quite literally hit from the sky when he didn't expect it and out of f reflex turned back human.

"I'm... alive?" He jokes weakly, smiling awkwardly at Superman's stare.

Danny considered this awkward.

Clark was processing the fact Lex Luthor somehow managed to bring back someone from death, his hands now full of said miracle and—

Shit, does the kid even have family left? What's he going to tell Lois!?

[terrestrialnoob]

Damian had never seen another person his age before.

“Wow, you're good at that.”

Damian froze in his practice and looked over at the boy. It was after his lesson, his instructor had other students to teach, and Damian had his own private training area. Well, it was supposed to be private. “Who are you?”

“Danny, what's your name?”

Damian glared at the boy. Who doesn't know who he is? “I am Damian Al-Ghoul, grandson of the Demon's Head, son of the Bat, heir to the League of Assassins.”

“Wow, that's a lot... Can I just call you Damian?”

“Servants call me Master. How did you get here?”

Danny shrugged, “I was just looking around.”

“Just looking around...”

“Yeah, my parents are in the science lab down in the bottom basement with the weird lake and I was helping them, but then I got board and Jazz said I wasn't allowed to leave the lab, but when I asked Dad, he said I could do what I want as long as I don't get in trouble.”

“Oh, the idiot scientists.” Damian remembered how his mother had described the new scientists hired to study the Lazarus Pools. A pair of geniuses when it came to the scientific study of magic but idiots in all other fields. Surely only idiots would bring their children to live with the League of Assassins.

“What do you mean? If you're a scientist you can't be an idiot?”

Damian huffed at the boy. “You can be smart at one thing and dumb at others. Like you could be good at reading but bad at numbers.”

“Oh, I guess that makes sense. But I'm pretty good at reading and numbers.” Danny then smiled brightly, “It looks like you're really good at swording though.”

“It's called swordplay. And yes, I am good at it. Better at it at my age than many who are older.”

“Can you show me how to do it?”

Damian contemplated for a moment, “As long as you don't get in the way of my practice, I don't see why not.”

Danny cheered as he ran up to where Damian was standing, but Damian pointed to the side of the training area, “There should be a spare sword over there you can use.”

Danny nodded and ran to get it then ran back.

Damian wasn't sure if he'd like showing Danny how to use a sword, but he liked how Danny followed all his instructions. It was different than how the servants followed his orders, but Damian couldn't place why. It became common place, for Danny to show up after Damian's lessons and Damian would show him what he'd learned. It actually made learning new things easier because Damian had to figure out how exactly something worked in order to show Danny how to do it. Not only that, but when they practiced the moves on each other, Danny would change them and make it harder to beat him. Damian did win every time, but Danny wasn't half bad.

[thankchaosforspellcheck]

Al Ghul twin ramblings

Something really interesting about the dpxdc crossovers that have Danny and Damian as twins that I've never seen anyone talk about is the bit of mirroring imagery going on there.

Like, Danny is literally everything that the Wayne family, consciously or unconsciously, would give Damian grief for not being.

He's better socialized, easy to get along with, has the snappy banter and peppy attitude Robin was known for as well as a quick wit that helps him figure out clever ways to deal with difficult situations.

Damian has better training and the attitude rich socialites would expect from a child of a wealthy family, but he's not going to be able to fake the ease and friendliness of his predecessors for a long time, if ever. He's certainly made Robin his own, but he's never going to match up to the picture everyone has in their head of what Robin is supposed to be like.

Does Damian ever think about this? How, if their positions were swapped and Danny had been sent to their Father and he had been cast out to the Fentons, Danny might have taken to the mantle of Robin so much easier than he had?

and if that's true, could Damian say the same? Would he have been able to protect Amity Park while balancing school and a social life, all while keeping himself in check and only using non-lethal force?

Would he have even made it that far, or would he have run away at the first opportunity?

Would he have even been able to survive the accident Danny went through, or would he have burned to a crisp instead?

[that-weird-thing-in-the-woods]

:) I’m backkkk you all thought you could get rid of me

🛕Pharaoh Tucker with his “Wifes” Sam and Danny🛕

Yes I’m bringing attention to this like why is nobody talking about this????

Now let’s get into the main plot so Danny, Sam and Tucker have to GO and fast ( GIW or bad Fenton au either or. !!!Bonus points!!! If Danny got hurt and than it would make this so much funnier y’all get what I mean in a sec) and they all go to the ghost zone where they meet up with clockwork and he tells them that one of Tuckers earlier reincarnation made a place so in the future he’s good even if he doesn’t remember it so clockwork brings them to what looks like an ancient Egyptian empire with the civilians and the people who live there as the people who died in the past {sorry if this is a bit hard to read I am very tired} and they are brought to the place where clockwork just casually reveals that Tucker is the pharaoh ie: The King and Sam, Tucker and Danny take this very well for them this is a safe place for them to heal and live with the added bonus of helping with Danny’s obsessions (Protection and Space) and after a bit they gain the affection of the people and the…Protection of the people??? Because for the people they see that one of their queen (Danny) was hurt before the royals came here so they get a bit protective and for a bit of information here’s the main jobs of the trio

Tucker taking care of the rules and doing the main running of the empire

Sam takes care of the army and gardens of the empire ( making sure they have enough food and such )

Danny takes care of the people (who grown the most fond of ) and such

So you can see what I’m going for with this now here’s where the JL comes in so the empire was NOT in the ghost zone it is in its own little world but somehow the JL gets tipped off about a triving empire that NOBODY has made contact with so a group ( Batman, Superman, Wonder Woman, the flash, green lantern you know the works) goes to make contact and hopefully make allies with them so they go and are taken aback a bit by how much this place is triving and what to meet the people who made this happen so what the JL was expecting was a lest a adult but instead they got what looked like a 16-17 with what looked like two people the same aged sitting next to him on either side (!!!EXRA BONUS POINTS!!! If one of the supers helped Danny before the meeting) and someone makes the dumb decision to ask them where are the REAL rulers and the guards in the room ( who I forgot to mention ) get mad at them and become hostile to them and Sam has to clam them down and that’s all for the plot at the moment

Now on to the details let’s start with tucker I’m thinking about this

( just instead of blue it’s red) and for a head piece I’m thinking the good old classic 

It just fits

Now for Sam I’m thinking is for her outfit

But in darker colors because she’s SAM and for a head piece I’m thinking something like this

Nothing to big because she has to train the army and she’s outside a lot so if it’s anything to big I think it will just be annoying

For Danny this

Mixed with this

Because ye and for his hair piece I’m braining

This I think it looks neat

Now that’s all from me byeee

[killershark82]

Honestly ezra lost in wild space (I miss my son😭😭) is such good crossover material like:

Especially if you do smth fun like incorporate his connecting to animals into it

Imagine Ezra in Pokémon just accidentally befriending all the legendaries

Imagine him in httyd just chilling with a bewilderbeast, hatching little baby bewilderbeasts and just being the random guy that shows up from time to time giving random but accurate information

Ezra going back to his feral gremlin self a little bit on his travels, just this feral guy who’s good with animals and somehow befriends almost anyone that’s tried to kill him ever

There’s just so many options, I love it

[indigosabyss]

Can Dark Gwen Poole meet Alastor?

OOH YES.

Like she can't die. But if she thinks its just cool to pop into hell, then she will. And obvs she'd go for the most popular Overlord in the Real World's eyes.

DGP is basically an Overlord who is still alive. And I think her love for unabashed violence would be something Alastor can get behind.

And she pays tribute to their newfound friendship by letting him commentate the tourney to the death she's set up between all the other Overlords.
