AO3 absolutely dominates this particular pairing. Their tagging system is unparalleled—you can filter for exactly the dynamic you want, whether it's established relationship, slow burn, hurt/comfort, or the specific flavor of mutual pining where Kirishima is the sunshine trying to thaw Bakugou's perpetual winter. I've found stuff there I've never seen mirrored anywhere else. The quality bar tends to be higher too, maybe because writers invest more time when they're tagging for a proper archive.
Having said that, I'd be remiss not to mention the old-school vibes of Fanfiction.net. The search function is a nightmare, no lie, but there's a certain charm in trawling through pages. You'll stumble upon fics from 2016, 2017, the golden age of the ship's rise, that have this raw, earnest energy AO3 sometimes polishes away. It's like digging in an archaeological site.

Honestly, a lot of the fics I've seen lean into the whole 'two sides of the same coin' thing. They're both steel-hardening heroes, right? So you get a ton of competitive 'sparring that turns into something else' plots, or gym buddies to lovers. It can get repetitive. The ones that stand out for me are the ones that play with their differences—like Tetsutetsu's more straightforward, brash personality clashing with Kirishima's underlying insecurities. There's a good one on AO3 where Tetsutetsu helps Kirishima train after a particularly bad fight where his hardening failed, and it becomes this really gentle exploration of vulnerability that neither of them is great at talking about.
I'm less into the modern AUs, but even there, the dynamic often centers on this boisterous, supportive friendship that just… tips over. Like, they're already so physically affectionate and loud with each other in canon that writing the romantic tension is almost about them not noticing what's obvious to everyone else. The fanon that they have a shared workout playlist is adorable and shows up everywhere.
Honestly, my favorite niche is post-war fics where they're dealing with the physical and mental aftermath. Their quirks are so tied to their bodies and their sense of self-protection; exploring how they rehabilitate each other, with Tetsutetsu's stubbornness mirroring Kirishima's determination, hits harder than another 'who can lift more' competition.

A lot of it circles around this intense, almost competitive loyalty. You’ve got two guys with the same Quirk but completely opposite personalities, and writers love to explore that push-and-pull. Are they rivals trying to prove who's more 'manly'? Are they best bros who'd take a bullet for each other? Both, usually. The plots often involve one of them getting hurt—physically or emotionally—and the other having to step up, which leads to a lot of protective moments and eventual realizations. There's also a ton of fics that dive into the insecurity angle; maybe Tetsutetsu feels like he's just a copy, or Kirishima feels he isn't living up to his own ideal. It's surprisingly introspective sometimes, beneath all the action and banter.
You'll find a lot of 'mutual pining disguised as friendship' stuff, too. Training sessions that get a little too intense, shared rooms on school trips, that kind of thing. The 'hardening' Quirk is a great metaphor for emotional walls coming down, so a lot of authors run with that. I stumbled on one where they kept challenging each other to see who could withstand more pressure, literally and figuratively, until they just cracked and admitted everything. It was a bit on the nose, but it worked.

The way writers handle Tetsutetsu and Kirishima's friendship in fanworks always circles back to the central conceit of their Quirks—two guys with hardening abilities, one steel, one rock. It's the ultimate 'same, but different' setup, and that's where the real fun begins. Most stories I've clicked on use that mirrored power as a metaphor for their entire dynamic. They're rivals, but in that deeply respectful Shonen way where they're each other's measuring stick. You get a lot of gym scenes, training montages, competitive eating challenges... it's all about mutual betterment through friendly conflict.
But the more interesting fics, for me, are the ones that dig into the differences the mirror doesn't show. Kirishima's insecurity is more overt, his 'unmanly' moments are a big part of his arc. Tetsutetsu, while loud, often comes off as more naturally self-assured. So you see stories where Kirishima is quietly envious of that, or where Tetsutetsu fails to understand why his 'bro' is so hard on himself. It adds a layer of depth beyond just 'they punch stuff together.'
A surprising niche I love is the 'found family' angle that pairs them with other Class 1-B or 1-A students. Like, a fic where Tetsutetsu becomes Kirishima's bridge into a more relaxed social circle outside of Bakugou's intense orbit, showing a softer side of their bond where it's not all about proving toughness. Those often have the best casual banter, the kind that makes their friendship feel lived-in and real, not just a narrative foil.

Man, the 'Tetsutetsu Tetsutetsu' and Kirishima dynamic is such a solid base for fic. I think the best tropes really dig into that mirror-match energy they've got going on. Identity exploration is a huge one—like, what does it mean to be 'the manly one' when there's another guy who's basically your copy? You can do some great internal conflict with that, maybe have one of them struggling with feeling like they're just a copy of the other while the other feels like they're living in a shadow. It's a neat way to interrogate their canon motivations but in a more intimate setting.
Then there's the classic friendly rivalry turning into something more. That's always fun because their competitiveness is already baked in. Scenes where they're trying to one-up each other in training, or in stupid domestic stuff like who can cook a spicier curry, just naturally lend themselves to that 'oh' moment of realization. Plus, the sheer physicality of their quirks and personalities opens up a lot of action-heavy or injury comfort scenarios that feel very true to character. A good hurt/comfort fic where one of them pushes their hardening quirk too far and the other has to step in is basically canon-adjacent at this point.
I've also seen a few really interesting fusion AUs? Like, putting them in a setting where their quirks are still a factor but reimagined, maybe as blacksmiths or knights. It strips away the hero-school context and lets you focus purely on the bond built through shared strength and values. Honestly, the tropes that work best are the ones that remember these two aren't just loud and hard; they're deeply earnest, and that earnestness is the heart of any good story for them.

Finding quality crossovers for this specific dynamic can be tricky because both characters are from the same source. The pairing you're after usually gets folded into larger 'My Hero Academia' fusions, rarely being the central focus. The best results I've had weren't by searching for the pairing directly, but by hunting down well-regarded crossovers where Bakugo or Midoriya is the main character. In those massive fics, Tetsutetsu and Kirishima often end up paired together as a side element, written by authors who genuinely get their bromance.
Archive of Our Own is obviously the main hub. Use the 'Crossover' tag filter on the main 'My Hero Academia' fandom page, then add the 'Kirishima Eijirou/Tetsutetsu Tetsutetsu' relationship tag. Sort by kudos or bookmarks. Be prepared to sift; the truly top-rated ones are often years old and might be unfinished. I'd also recommend checking out FFN's crossover section, even though the tagging is worse, because some legendary older fics never migrated.
Honestly, the highest kudo'd fic I remember that featured them prominently was a 'My Hero Academia'/'One Piece' story where they were part of a joint hero/pirate crew. The author nailed their competitive yet supportive energy. It's a real deep dive, but those niche finds make the hunt worth it.

Really, for me it's how they mirror each other. Tetsutetsu and Kirishima are these two guys who built their whole identity around being 'hard' and unbreakable, right? But their fanfics dig into the softness underneath all that. The compelling part isn't the similar Quirks, it's the similar insecurities. They both had to become who they are through sheer force of will, overcoming feeling weak or cowardly.
Seeing them recognize that struggle in each other, without having to say it out loud, creates this instant, deep understanding. A writer can have one of them get hurt—not physically, but emotionally—and the other just gets it. The comfort scenes hit different because they're not about being coddled; it's two rocks leaning on each other, knowing the other won't crack. It turns the 'manly' ideal on its head, showing that real strength is being vulnerable with someone who gets it.
That dynamic also fuels great conflict, though. What if one of them thinks the other is compromising their 'manliness' by catching feelings? The angst writes itself, but the resolution always feels earned because their bond is so foundational. It's less about romance and more about two souls finding their reflection.
