This is simply a collection of ideas for crossover fanfic that I wish were made. Y'all can use them however you see fit.
1. the dragon Prince/trollhunters crossover
"the trollhunters get teleported to the Dragon Prince world after an accident with Blinky experimenting with spatial Magic"
You are free to change how they got there, though I would prefer that blinky and aaaaargh be there you are free to exclude them if you want
2. Black Clover/RWBY crossover
"team RWBY, JNPR and Qrow get teleported to the world of Black Clover"
how they get there as your decision, whether or not Qrow and/or team JNPR is there is also your decision would also like the possibility of Black Clover characters getting their auras unlocked
3. Black Clover/World of Warcraft crossover
"Finral Roulacase has got his hands on powerful experimental space/time magic item and while he's testing it he accidentally ends up getting himself, the entire Black bull Bass along with everybody in it teleported onto Azeroth"
what expansion and where they end up is your decision. how, when and where he gets the item, and what causes it to go haywire in the first place is also your decision
4. Steven Universe/Infinity train crossover
everyone is who watched Steven universe future knows that Steven would definitely qualify for getting sent to the infinity train whether or not it can help him is the question
5. Multiverse self insert mega crossover
"you're the newest recruit to an interdimensional organization. Our mission, survival or Revival of endangered or extinct intelligent species, how we do this you say? By planting colonies on as many different worlds in as many different dimensions as you possibly can! Your first mission plant colonies of these 3 species: saiyan, namekian and kryptonians in the animorph universe good luck you're going to need it"
basically the story is an Adventure/civilization building story with all the conflict in drama that comes with it finding the right world's to build on, how they will deal with how to the natives of said planet/universe Etc you get the idea, entirely up to you if you go with my beginning setting or not just make sure to keep the main theme in mind
6. Multiverse mega crossover/fate kaleid liner Prisma illya OC self insert
"You have figured out how the Ainsworth family make the servant cards and you started making your own but then you thought of something why just the heroes of one world? If the Multiverse theory is to be believed should there be universes of every anime, manga, comic and cartoon out there? you begin making interdimensional portals to other worlds add a device to scan that's World's heros so that you can implant them into the Holy Grail system so that you can make servant cards of them question is how are you going to get close?"
basically this is an adventure across the Multiverse, the kind you can have all kinds of fun with also like a possibility should you ever visit the Black Clover universe try giving asta a copy of excalibur to see if his book will absorb it
7. Kaijudo: Rise of the Duel Masters/Godzilla
can't think of a proper synopsis for this all I can say is it would be epic see how they would react to having Godzilla show up and wreck the place, plus the the evolution serum and how it may or may not affect him
8. Ben 10/Kaijudo: Rise of the Duel Masters
"kid Gwen and Ben finally get back from space after their harrowing adventure to stop the Omnitrix from self-destructing and are middle of giving their grandpa Max a big hug when a portal appears out of nowhere and swallows them and the rust bucket hole when they come to they find themselves in the city they've never heard of San Campion they get into the rust-bucket and drive around to to investigate their situation until they encounter a giant monster attacking, Ben goes hero to stop the monster but quickly encounter a group calling themselves the Kaijudo Masters which mistake him for a kaiju one misunderstanding in a brawl later they come to explain their circumstances to the Kaijudo Masters can Ben & the Gang get back home while helping their Newfound allies fight off the choten"
obviously there's a whole lot of fun that can be had with this setup Ben's alien forms constantly being mistaken for creatures of the Kaiju Realm by dual Masters and kaiju alike, the way these characters personalities would Roll off each other and the fights it be a ton of fun Plus at the end of the series Ben's to'kustar form Way big would be able to get the monarchs out of the null zone
9. Fairy Tail/Kaijudo: Rise of the Duel Masters
"a mysterious note with unknown words written on it and guess who goes and reads it Natsu getting himself Lucy, Gray, Happy and Erza teleported to San Campion where the raw magical power draws the Kaijudo Masters do them Antics ensue can fairy tales Ultimate Team get back home while helping their Newfound allies in their battle against choten"
much like the Ben 10 story this would also be very fun for many of the same reasons Natsu's fire eating, Lucy's celestial spirit Magic, Gray's Ice make magic and Erza's requip Magic would leave all the Kaijudo Masters completely shocked
10. RWBY/SAO Alicization
the thing I haven't seen done with this combination is finding a way to transport team RWBY to those game worlds without those games being in the world of Remnant, the whole the game exists in the Remnant and they end up playing and getting trapped never really appealed to me and then actually getting transported to to those worlds seems a lot more appealing and fascinating to me for instance it leads the potential up probabilities of unlocking aura in the world were it never normally existed
11. self insert/Spirit animal/monster hunter
"you accidentally get killed by God/Goddess(your choice which one) feeling apologetic he gives you the option to reincarnate into any world you want with any variety of powers you want within reason and you get to thinking what world would I want to go to the end up thinking the spirit animal world be a decent place to live in, no cosmic madman showing every now and then to the blow up the world, the only real threats are any of all of the great beasts and there followers which if I were to use my monsties from Monster Hunter stories it would make surviving there pretty easy so you asked him/her to reincarnate you into the the world of spirit animals with access to your all your monsties, your kinship Stone along with the option of getting my own spirit animal and off you go reincarnated a new without even the slightest idea and just how much the spirit animal world is about to change because of you"
now this stories got all kinds of potential you can do with it, from the potentially epic fights between your monsties and the great beasts, how having your monsters there may or may not cause monsters from the Monster Hunter Universe getting during the spirit animal summon ceremony overall a very interesting and potentially awesome story if in the right hands
12. animorphs/spirit animal
we can all probably imagine the potential this particular idea has for obvious reasons, need I say more?
13. Dinosaur king/spirit animal
can't really think of a summary and just like the last one this one do it have a ton of fun story potential by not as much as the last one but it would be a significant amount
14. Milo Murphy's Law/anything
We can all imagine the kinds of fun we could have with this, having either Milo himself show up or somebody ending up with Milo Murphy's curse with the complete and utter chaos that would ensue would be comedic gold. Imagine your favorite show and then Milo shows up...😂😂😂😂😂😂 that would satisfy a chaotic part of my soul.
15. The Dragon Prince/World of Warcraft
do I've seen a lot of different versions of this crossover though I've not seen one that I personally was looking for and that is the accidental teleportation to either world which would lead to the Discovery, contacting, and th creation of portals between both worlds. Depending on the expansion could create any number of potential variables for instance which forces and/or races would potentially join either faction or would the beings of the Dragon Prince World formed their own third faction would make for a quite the interesting read.
16. self-insert Monster Hunter/Spider Rider
"you're minding your own business walking around the Wildspire waste gathering materials untill you find a portal and you think (
portals again, hasn't it been the third time this year, I wonder what's going to come out of this one this time?), then you feel it, a tugging sensation drawing you towards the portal (
shit, unless of course it's me going into it!). You try desperately to get away but the pulling sensation is too strong and you're pulled through the portal. As you're traveling through the portal completely unaware of where you're going you see a giant beautiful woman you do not know why but you feel compelled to grab her hand which she is stretching out towards you and so you do which causes upon contact a blinding light. You wake up to find yourself in an unusual forest unlike you any you've ever seen which is saying something because you been places, you find a strange boy right beside you calling himself Hunter Steel and he's just as clueless as you on where you 2 are. A few Misadventures later and you come to find out that you were in a place called the inner world where brave warriors ride huge spiders to battle an insectoid race called the Invectids and you decide to help them in their cause while you trying to figure out a way back home for some unusual reason though monsters from back home keep showing up here and wreaking havoc. Can you solve the mystery behind why monsters from back are showing up in the inner world and get back home while also fighting the invectid and their leader Lord mantid there's only one way to find out"
this is awesome storytelling potential and the setting would also work really well with monster hunter stories imagine the Spider Riders reaction to you riding monsters lol.
17. Fire Force/Fairy Tail
Natsu in the gang get transported the fire force world, enough said
18. Terra Nova/Jurassic world
Anyone who watch terra nova can imagine how epic this crossover would be.
19. fate kaleid liner Prisma illya/ Fate/
Zero
imagine if the characters of "fate kaleid liner Prisma illya" watched Fate/Zero
20. Heavy Object/godzilla
how is there not a fanfic of this, it would be fucking awesome
21. Monster Hunter/RWBY crossover
A god of chaos who hates both the brothers and there little mistake Salum, had decided to help the inhabitants of Remnant out by releasing all the monsters of the universe of Monster Hunter (excepted for the magala line because don't give Salum ideas) to fight the grim and provide food for them, along with altering some of the faunus that were still developing faunus trait to match that of the monsters. Even going out of his/her way to provide a monster encyclopedia in both book form and a downloadable version to notify them of what there in for, needless to say chaos ensues. Now Remnant is in for quite the change, how will the people of Remnant react and adapt to the new changes to there world?
22. Warhammer40k/multiverse crossover
Reporting to all multiversal travelers and gods, the Warhammer 40k section of the multiverse has been declared a dumping ground for gods that have dangerous species they don't want in there universe anymore but don't want to kill off. The species that have already been released are as followed: Saiyans, Daleks, Cybermen, Zerg, Xenomorphs, Yautja, Yuuzhan Vong, and the Borg with the only species not aloud to be released being the Flood, the Brother Moons and Mr. frundles which are banned species by multiversal law and are forbidden to be released outside of the universes they already infected. Ghost riders have also been released to try and rain in this chaotic section of the multiverse.
23. Pacific rim: The black/Monster Hunter crossover
the Precursors' kaiju have taken Australia driving most humans off the continent all while a god of chaos watches. Deciding it wanted to have a little fun so it choose to make it a little harder for the Precursors to keep the continent while also making it a little harder for the humans to retake the continent by releasing all the species of flora and fauna from the monster hunter realm that could live in the environment of Australia, elder dragons includes 😁.
24. Horizon: Zero Dawn/Monster Hunter crossover
A monster hunter is in the Ancient Forest on a Quest to hunt a Pukei-Pukei when a portal opens up and sucks him/her though knocking them unconscious on the way though, when they wake up there is a young women named Aloy, you later come to find out that you are on a different world.

Serina: A Natural History of the World of Birds (Speculative Evolution) I have same regular fanfic and fanfic crossovers ideas on this so here's the basic setting
A passing (god/goddess or super advance race) finds Serina during the ocean age of the Ultimocene they become curious and decide to analyze the moon studying it life and using powers/tech to look into its past to study its history, discovering the fact that the life of this moon was brought here and left to its own devices some 250+ million yrs. ago. that there were 2 living and 2 extinct sentient species that evolved from that introduced life, along with the fact that for some unknown reason the moon was dying, which would bring the other remaining sentient species (one of which had 3 subspecies!) to extinction. Unable to bare the thought of the loss of sentient life, the being/beings thinking "entirely different ways of thinking, different ways of feeling gone!" decided to revive the 2 extinct sentient species then take all 4 sentient species and some of the native wildlife that the 3 most recent sapient peoples evolved with (the wildlife of the Harp steppe along with the current wildlife of the ocean age, that includes the Strormsonor) to a more suitable star system to live in with first place they think to look being finding where there introduced ancestors came from.
You decide the where they end up. Is it earth? what time in earth's history they end up? is it a different universe? which one? Mass effect, Halo, Horizon: Zero dawn, Avatar: the last Airbender etc., When in those universes do you end up? there is so much potential with what you can do with this Idea.
25. Serina: A Natural History of the World of Birds (Speculative Evolution)/Earth modern times
Aaah yes humanity of the 2020s having to now share earth with 4 other sentient species along with the native wildlife of a ice age world being introduced to to the arctic circle, how fun, and would make for such an interesting read. The only race that wouldn't be in the arctic circle would be the Forked-tail Babbling Jays as the are a desert species so here is list of where they would live:
a. the deserts of the south to southwestern U.S.A. primarily in areas where it rarely snows with plenty trees to nest in and wildlife to hunt
b. Much of Africa would be the perfect home for them
c. The same could be said of Australia
26. Serina: A Natural History of the World of Birds (Speculative Evolution)/Avatar: the last Airbender crossover
Team Avatar having just escaped Zuko and setting off on their journey to help Aang master the elements and save the world... until them and everyone else day(including everyone who was a sleep) was rudely interrupted by an unknown entity calling itself (insert name) had decide that this would the perfect place to put the people and animals of a dying world to prevent there there extinction.
