Honestly, I get a little tired of seeing the same ones over and over. Yeah, MCU, HP, Naruto. They’re popular for obvious reasons, but it makes finding a truly novel crossover feel like a treasure hunt. I wish there were more with less obvious picks—like, I read an amazing one with 'Fullmetal Alchemist' once that explored Quirks vs. alchemy in a really smart way, but those are diamonds in the rough.
My personal theory is that it boils down to audience overlap and power-system compatibility. The big shonen fandoms share a reader base that’s already invested in battle mechanics and teenage heroes, so the crossover logic writes itself. The Western superhero stuff taps into that same power-fantasy vein. It’s not a bad thing, it just gets repetitive. I’d love to see more crossovers with slice-of-life or horror series, just to break the mold.

I lurk the AO3 MHA crossover tag a lot, and the big ones are pretty predictable once you start scrolling. 'Marvel Cinematic Universe' is absolutely massive—the sheer number of fics where Class 1-A gets dumped into New York or Spidey ends up at UA is wild. 'Harry Potter' is another constant; the 'wizard with a Quirk' or 'Midoriya gets a Hogwarts letter' premise has endless variations.
'Naruto' and 'One Piece' are huge in the anime/manga crossover space, which makes sense given the shonen battle genre overlap. You also see a ton of 'Attack on Titan' and 'Demon Slayer' crossovers, probably because of the dark fantasy and high-stakes fight elements. 'DC Universe' pops up a fair bit too, especially Batman or Superman meeting All Might scenarios.
It’s interesting though—you’ll occasionally get a surprise like a crossover with 'The Witcher' or 'Percy Jackson', but the feed is dominated by those first few I mentioned. The Marvel one is just its own beast, I think it might actually outnumber some of the anime ones.

Marvel, definitely. Then Harry Potter and Naruto. After that, it's a mix of 'One Piece', 'Demon Slayer', and 'Attack on Titan'. The archive stats on AO3 basically show this hierarchy. You can filter by the crossover tag and see the fic counts; those are always at the top. The DC stuff is there but less frequent than Marvel for some reason.

From what I've seen browsing and filtering, it's Marvel, Harry Potter, and then a rotating cast of other big shonen. The MCU tag is flooded, no question. It's almost a default setting for a lot of writers wanting to throw the MHA kids into a bigger, grittier superhero world. Harry Potter is the comfort food of crossovers for this fandom; the magical school trope fits UA's vibe in a weirdly seamless way.
'Naruto' is probably the next biggest anime crossover, followed closely by 'One Piece'. I'd put 'Demon Slayer' and 'Jujutsu Kaisen' as rising stars in the tag over the last couple years. The patterns are pretty clear if you sort by kudos or bookmarks—those fandoms have entrenched themselves.

I woke up as the Villainess, but instead of a halo, I got a Scythe.
However, my power has attracted the world's most dangerous monsters: A possessive Werewolf, a bloodthirsty Vampire, a Tentacle-wielding Professor, and a Biblically Accurate Angel with a thousand eyes. They think I'm their prey to be tamed, but they forgot one thing: I am Death itself.

Elina thought she had hit rock bottom.
She lost her job. Her therapy session dredged up memories of the ex-boyfriend who stalked and traumatized her. The only thing she had left to look forward to was the finale of her favorite fantasy series, Moonbound Faith.
Then the show ended.
The heroes won. The villain died. Everyone got their happily-ever-after.
That same night, a knock at her door shatters what little peace she has left.
Her ex is standing outside.
The man who was supposed to be in prison.
Forced to flee into a storm, Elina runs until she reaches the edge of a cliff with nowhere left to go. Faced with a choice between death and returning to the man who destroyed her life, she jumps.
But instead of dying, she wakes up inside Moonbound Faith.
Not as the heroine.
Not as a side character.
But as Luna—the infamous villainess whose tragic death she celebrated only hours before.
Determined to survive, Elina plans to use her knowledge of the story to change her fate. But everything she thought she knew begins to unravel when a small boy tugs on her sleeve and calls her one word:
“Mom.”
The original story never mentioned a child.
And when Elina uncovers the truth behind his existence, she realizes something terrifying.
The villainess was never the villain.
The story lied.
And the ending she remembers may not be the ending waiting for her at all.
At a time when sudden cosmic imbalances can be felt across universes, Earth becomes the center of an extraterrestrial attack when there is an alien-like invasion by an army of inter dimensional beings led by a goddess of war and death.
There is then a most impeccable ensemble comprising of one Natasha Johnson; Atlanta’s christened superheroine, ‘Viper’, along with a group of teenagers, super-powered beings, some old familiar faces, scientists, cops, the military, and even mercenaries who must then team up to ensure the survival of the planet as well as preventing the impending destruction of the entire cosmos.
*story completed* When the Black-fur Hades meets the no-fur Doll, he can just feel his comfortable life as a back-alley fixer slipping through his paw. Being contracted to take the no-fur away from trouble brewing with his mobster owners to a breeding farm upstate seems like a straightforward enough job. But when it comes to dealing with this particular no-fur, nothing is straightforward. Bestselling authors Hermit & Star have created another steamy, dark world - this time with anthropomorphic feline Alphas and their no-fur Omegas!
Man dies. His last act in the previous life generates him an absurd amount of karma. He meets a god, and it reborns him in a crossworld of Larry Potter and DxD. He gets a gift, one that can only be fully explored with the knowledge that he learned in his previous profession in the previous world. The keeping of knowledge is also a gift. And with that, his karma is spent.
Thrown in the world with a 'good luck' and a slap in the back, he fights to survive until the start of canons.
The time until that, 1000 years.
Yeah… Now read about some of his adventures in this crossed over world, beginning already in HP canon.
English is not my main language, so you will find some strange stuff, like the mix of North American and the Queen’s English.
Disclaimer: All characters that you recognize from the franchise of Larry Potter and DxD are propriety of its respective creators and I only wish that they were mine. But they are not. I only own the MC, the OCs, and the ideas that generated the non canon plot.
After transmigrating into a novel, I realized the heroine and I had the exact same name.
Naturally, I thought I had transmigrated into the female lead.
So I marched straight to the man who was still a broke nobody at the time, threw all caution to the wind, and pounced on him like I had plot armor protecting me.
He even glared at me with red eyes and told me he hated me. I honestly thought he was just into the whole push-and-pull thing.
Everything shattered when the real heroine showed up and I finally understood one thing. He actually hated me.
Heartbroken, I packed my bags and got ready to disappear.
The next second, he pinned me against the wall.
"Where are you going? Already bored of me, sweetheart?"
For a minute I thought you were talking about a specific AO3 collection, but that kind of dedicated, fandom-specific crossover archive is mostly an older fandom creature. 'My Hero Academia' crossovers are scattered all over, really. The primary organizational method is just tags on Archive of Our Own.
You'd typically filter for 'My Hero Academia' and then include a second fandom tag, maybe 'Marvel Cinematic Universe' or 'Jujutsu Kaisen'. Authors are pretty good at using relationship tags for the crossover pairings too, which helps. I remember spending a whole weekend just filtering for Izuku Midoriya & various characters from other series.
There isn't a single central hub. Some old forums or fanfiction.net communities might have attempted themed collections, but the tagging system has made that kind of dedicated archive less necessary, even if it's a bit messier to navigate.
Alright, so you're looking at the 'My Hero Academia' section on a big site like AO3, yeah? The key thing is tagging it right. It's not just slapping on 'MHA' and 'crossover'—you gotta use the fandom tags properly. For the main crossover, you'd tag 'My Hero Academia' and whatever the other fandom is, like 'Marvel Cinematic Universe'. The system should link those under the 'My Hero Academia' fandom page.
Make sure you pick the right archive warning or 'No Archive Warnings Apply'. People filter hard for that. Then, get specific in the additional tags: 'Crossover', 'Alt Universe', maybe 'Quirkless Midoriya Izuku' if that's your angle. A good summary that actually says what happens helps a ton. Honestly, half the battle is making it findable for the weirdly specific thing someone is searching for at 2 AM.
So this is probably going to sound like a weirdly specific rec, but the 'My Hero Academia'/'Monster Hunter' crossover that’s just called 'Monster Hunter: MHA Edition' over on the archive is the most bizarrely cohesive thing I’ve ever read. It doesn’t just drop the characters into the other world; it rebuilds Quirks as a form of biological adaptation that fits the 'Monster Hunter' ecosystem. The author has All Might facing down a Rathalos, and it’s not played for laughs—it’s this desperate, awe-inspiring clash that actually respects the scale and danger of both franchises. I was skeptical until I hit chapter three, where they explore how Support Gear would evolve in a society built around hunting giant monsters instead of villain fights. The world-building logic is airtight.
It’s a slow burn, with long stretches focused on crafting and survival, which won’t be for everyone. But if you ever wanted a story where Midoriya’s analytical mind is applied to monster weak points and environmental traps instead of hero techniques, it’s a fascinating character study. The pacing can drag during preparation phases, but the payoff in the actual hunt chapters is immense. I found myself more tense reading about a well-placed shock trap than most final boss fights in other fics.
