All Might X Deku Novels & Stories

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.

The best tropes for this pairing are the ones that let both characters evolve beyond their canon roles. I'm always drawn to fics where Toshinori is forced to confront his own crumbling legacy head-on, not just as a symbol but as a deeply flawed man. Seeing Deku inherit One For All is one thing, but watching him also inherit the crushing weight of All Might's mistakes and unresolved trauma? That's where the real development lies.

Time travel's been done a lot, but I love the versions where a post-war, broken Deku lands in the past and has to rebuild a relationship with a pre-injury, arrogant All Might. The dynamic flips completely—Doshinori has to learn humility from his own future successor, and Deku has to unlearn his hero worship to see the man as a partner. It dismantles the pedestal on both sides.

A less common trope I adore is 'mentor loses his quirk first.' Instead of the injury being a distant memory, what if it happens during Deku's tenure as a student? Watching All Might navigate sudden, total vulnerability while trying to guide a protege who still needs him, and Deku stepping up not just as a hero but as a caretaker, forces monstrous growth. The power imbalance evaporates, and they have to find a new footing.

Sometimes the simplest premise works best: just put them in a room for a long, difficult conversation after Kamino. No powers, no villains, just the emotional fallout of shattered ideals and the slow, painful process of building something real from the debris.

The mentor-mentee setup between All Might and Deku in the original series is already intense, but fanfiction strips away the public hero veneer and digs into the private weight of that legacy. Stories often push All Might into a more active teaching role post-injury, dwelling on his physical decline and Deku's panic about measuring up. I've seen fics where All Might actually sits him down to discuss the psychological toll of One For All, not just the smashing—something the anime glosses over.

What's compelling is how writers use the ship to heighten the dependency. When the relationship turns romantic, the power imbalance becomes the central conflict. It's not just 'can he be a worthy successor' but 'can he be an equal partner when his idol literally passed him the torch.' The best ones don't solve that tension easily; they let Deku struggle with seeing All Might as a fallible man, not a symbol. I read one where Deku freaks out after their first kiss because it felt like betraying the hero-worship, and All Might has to navigate that minefield. That messy emotional work is what keeps me searching for more of these stories, even if the tag is mostly fluff or smut.
