How Can I Publish My Work On My Hero Academia Crossover Archive?

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.

The crossover archive's upload system looks more complicated than it is once you get past the tags. The dropdown menus for selecting both canons are straightforward, but where people trip up is the relationship tagging. I've seen so many submissions get lost because someone tags Deku with one universe's character but forgets to tag the dynamic between them, so it never shows up in certain filters. My process is: draft in a separate doc, get the crossover premise solid, then copy-paste into the submission form and triple-check the fandom tags. Honestly, the hardest part isn't the tech, it's making sure your story actually fits the archive's vibe. Some crossovers get buried because they're just a scene, not a proper story. I aim for at least a full chapter that establishes why these worlds are colliding. The archive mods are pretty chill about content, but a coherent plot helps your work get noticed and recced in the community threads.

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.

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.
