What Are The Best Dabi X Deku Fanfiction Tropes To Explore?

I think a lot of people default to the childhood friends to enemies to lovers pipeline, which is fine, but I’ve really warmed up to the ones that play with the aftermath of their actual canon dynamic. Like, stories that start after the war arc, where Bakugo’s apology is this massive, unspoken weight between them. The best trope for that is the ‘forced proximity’ during pro-hero work—they get assigned as a permanent duo by the agency, and they have to figure out how to communicate without all the old explosive shorthand. It’s less about rehashing the bullying and more about two incredibly competent people learning a new language for partnership. The tension isn’t will-they-won’t-they, it’s can-they-build-something-stable-out-of-the-rubble. I also have a soft spot for role reversal AUs that aren’t just ‘Deku has a quirk’. There’s this one where Bakugo is the one who gets OfA, and Midoriya remains quirkless but becomes a tactical analyst for hero agencies. Their dynamic flips entirely; Bakugo has to shoulder this unbearable legacy, and Deku becomes the calm, strategic center he resents needing. It explores their rivalry through a completely different power imbalance. The pining hits different when Bakugo is the one feeling unworthy of the admiration. Honestly, I skip anything that glosses over their damage too quickly. The best tropes let them be messy, let them yell, and let the healing feel earned, not inevitable.

I find the most interesting takes on Deku and Dabi often lean into speculative 'what-if' scenarios. These dynamics aren't the most common pairing in 'My Hero Academia' circles, which makes the existing stories particularly creative in how they bridge the vast ideological and moral gulf between them. Authors have to build a plausible bridge, and that's where world-building-heavy genres really shine. I've seen some fantastic alternate universe pieces, especially ones where quirks manifest differently or where family lineage takes a different turn. A story where Izuku Midoriya is actually Touya Todoroki's younger brother, for instance, creates an immediate and intense foundation. The emotional core isn't romance at first; it's about shared trauma, hidden identities, and the crushing weight of family legacy, which feels very true to the original material's themes. Then you have the more action-oriented genres, like hero/villain conflict or undercover operations. These are great for exploring their dynamics through force and friction. A plot where Deku, perhaps as part of a new intelligence unit, has to infiltrate the League of Villains and ends up forming a twisted understanding with Dabi offers so much room for psychological tension. It's less about friendship and more about a deadly game of cat and mouse where mutual recognition of sheer, stubborn willpower becomes a weird form of respect. The conversations in these fics crackle because they're laced with threat and philosophical debate about hero society's failures. For something completely different, crossovers can throw them into a new context that strips away their usual roles. Imagine a fantasy AU where Dabi is a rogue fire mage cursed by his own power and Deku is a healer or a scholar trying to understand the magical corruption. Without the rigid structures of heroes and villains, their interactions can develop along entirely new lines, driven by necessity or a shared goal against a common foe. The genres that work best are ultimately the ones that provide a strong external pressure cooker to force these two very distinct, damaged, and fiercely committed characters into prolonged contact, letting the sparks—whether of conflict, reluctant alliance, or something more—fly from there. I'm always hunting for fics that use those genre frameworks to really dig into the potential of that contrast.

I spend way too much time poking around that corner of the fandom, honestly. The 'brotherly angst' trope is huge, obviously. Everyone loves writing about Shoto discovering Dabi's identity, the fallout from that, the slow and painful attempts at reconciliation. It’s less about redemption and more about navigating this awful shared history. I've seen a lot of AUs where they're raised together from the start, which erases the canon trauma but creates a whole different dynamic—protective Touya, jealous Shoto, that sort of thing. The fandom also has a weird fascination with making them roommates in college or pro-hero settings, forcing proximity on them. It can get pretty dark, exploring themes of legacy and parental failure, or surprisingly domestic if the writer just wants them to awkwardly share an apartment. Some of the best fics use the 'mutual understanding' angle, where Shoto is the only one who can see through Dabi's anger because he recognizes the same cold fire Endeavor left in them. It’s less about romance and more about a messed-up, profound connection. I avoid the super OOC fluff pieces, they just don't feel right for these two.
