All Might X Deku

The whole 'Dadmight' thing has basically taken over the 'My Hero Academia' fandom at this point. It's not just about All Might being a mentor to Midoriya anymore; it's morphed into a full-blown family dynamic. I've seen so many fics where All Might ends up formally adopting Izuku, dealing with parent-teacher meetings, or just the two of them figuring out domestic life while hiding One For All secrets from Inko. It's the ultimate found-family comfort food.

There's also a surprising amount of time-travel or dimension-hopping centered on them. Older Izuku getting sent back to his quirkless days and having to navigate a relationship with a younger, more vulnerable All Might creates this fascinating tension. You get to see All Might's perspective shift as he watches this kid display wisdom and trauma far beyond his years. It flips the mentor-student script completely, which is probably why it's so addictive to read.

The most common thread I see is Dadmight, obviously. Mentor All Might struggling with the reality that he's basically given this scrawny kid a death sentence with One For All, then having to deal with the emotional fallout of watching that kid nearly destroy himself over and over. It's not just fluffy found family stuff either—some of the best fics dig into the guilt. Like, All Might retired, he's supposed to be done, but now he's having nightmares about young Midoriya ending up just like him, hollowed out and alone.

A surprising amount explore time travel or dimension travel. Midoriya ends up in a world where All Might died earlier, or All Might wakes up decades in the past with all his future knowledge and has to prevent his own mistakes. Those get weirdly philosophical about legacy and inevitability. There's also a subset that's pure hurt/comfort, where All Might finds Midoriya after a villain attack or a bad day at school and just... sits with him. No grand speeches, just quiet presence. It hits different than other pairings because the power imbalance is so baked into their canon relationship—exploring the shift from symbol to person feels huge.

Occasionally you'll find darker AUs where All Might is the villain, or Midoriya turns villain and All Might has to face him. They're rare but memorable when done right, usually focusing on the tragedy of the disciple surpassing the master in the worst way possible.

I’ve always thought All Might and Midoriya’s dynamic gets twisted into some wild shapes. Beyond the obvious mentor-student thing, a lot of writers push the 'found family' angle super hard. I stumbled across this one series where All Might officially adopts Izuku after Inko passes away, and it’s less about fluffy comfort and more about the sheer, crushing weight of that legacy now being a legal responsibility. The fics that explore All Might’s deteriorating health from Izuku’s terrified perspective hit different—like, he’s not just watching his hero fade, he’s realizing he might have to be the one to catch him when he falls.

Then there’s the darker side, which I admittedly browse with morbid curiosity. AUs where All Might is the villain, or where Izuku’s admiration curdles into resentment after discovering some hidden truth about One For All’s origin. They’re not my usual taste, but the psychological unraveling can be weirdly compelling. Makes you question the whole 'symbol of peace' idea in a way the manga never really dares to.

Most of the time, though, the evolution is just a slower, softer version of canon. It’s cozy. Sometimes after a rough day, that’s exactly what I’m looking for—no subversion, just the steady warmth of a bond that’s already solid.

Honestly, I don't really seek out specific ratings for that pairing anymore. The fanfic scene for 'My Hero Academia' is so huge that 'top-rated' often just means the most popular or most kudos'd on a site like Archive of Our Own, which can be skewed toward longer fics or certain tropes. I've found some real gems with fewer kudos by filtering for completed works and specific tags like 'Mentor All Might' or 'Injury Recovery'.

Sometimes the best stories aren't the ones with the highest numbers. There's one called 'Worth a Thousand Words' that's a photojournalism AU that just nailed their dynamic, but it's not in the top pages because it's a one-shot. I'd start on AO3, use the relationship tag, and then sort by bookmarks instead of kudos—it's a bit of a better signal for quality, in my experience. Then I'd just start reading summaries that catch my eye.

Finding good All Might and Deku fanfic really depends on how you read, honestly. I’ve been in this corner of the BNHA fandom for a while, and I keep three tabs open: Archive of Our Own for the curated, deeply-tagged longfics, Fanfiction.net for that classic, massive archive feeling, and then I lurk on specific BNHA Discord servers for the real-time, chat-feed style snippets and drabbles.

AO3 is unbeatable for the father-son, mentor-protégé dynamic—you can filter by 'One for All Legacy' or 'Hurt/Comfort' and find exactly the emotional weight you’re craving. I found a haunting series there where a retired All Might guides a struggling Izuku through the political mess of hero society, and it just nails the quiet pride in their relationship. Meanwhile, FF.net still has those epic, decade-spanning AUs from before the manga even finished, the kind that built whole universes. And the Discord snippets? Sometimes a writer will drop a 500-word scene of them sharing a bowl of katsudon after a rough day, and it’s more potent than a 50k epic. You gotta cast a wide net.

My secret weapon is following the authors, not the platforms. If someone writes a stunning All Might & Deku piece on Tumblr, I’ll track their AO3 crossposts or their Carrd for original fiction links. The good stuff tends to migrate or get mirrored.
