What Are The Most Popular Midnight X Deku Fanfiction Plots?

I've wandered through the tag for a while now, and honestly? The 'hero training gone wrong' premise is everywhere, but it's the variants that stick. Lots of fics play with the idea of a parallel universe Deku showing up—either a version who never got One For All or one who went completely villain. The tension comes from our Deku confronting a reflection of his own potential failures. Then there's the internal split fics, where some quirk accident or psychic attack literally divides him into multiple personalities or physical copies. Those get messy fast, but the best ones use it to explore his self-sacrificing nature from an outside perspective. Like, one Deku seeing another constantly break his bones and finally understanding how terrifying that looks to everyone else. It's less about romance and more about intense self-analysis through a surreal lens. A smaller subset I keep clicking on are the time-loop stories, where he's the only one aware of the reset. Watching him slowly build a rapport with his past self, trying to guide a more naive version without breaking everything... that's where the real character study happens. The ship tag feels almost incidental in those, just a framework for the introspection.

Look, I gotta be real – this is one of those pairings where the most popular storylines are less about romance and more about radical character surgery on Mineta. You’ll find a ton of 'Mineta Redemption' or 'Mineta Has a Secret Quirk' AUs. The premise is basically erasing his canon perversion and turning him into a secretly brilliant strategist or giving him a hidden, powerful mutation. Sometimes Deku is the catalyst who sees this 'true' potential, which builds their bond. Another huge category is role-reversal or 'swapped places' tales. What if Mineta was the quirkless one Deku defended in childhood, and they became underdog bros? Or the inverse – Mineta gets One For All through some wild accident. These plots thrive on upending the established hierarchy, making their dynamic central to the new world order. Then there’s the 'hurt/comfort' pipeline, often post-battle or after a villain attack. Mineta gets severely injured, and Deku, being the empathetic hero, is the one who visits him, leading to deep conversations and a shifted perspective. It’ army less about shipping tropes and more about using Deku as a vehicle to force Mineta into emotional growth. The popularity seems tied to a desire to fix a disliked character through the lens of the fandom’s favorite cinnamon roll.

Really depends on how you define 'popular,' I guess, but from where I'm scrolling, hurt/comfort with a technological twist is huge. Deku's habit of self-sacrifice meets Kaminari's post-overuse short-circuiting, and you've got this cycle of them patching each other up, both physically and emotionally. It's not just bandaging burns; it's rewiring faulty support gear or figuring out workarounds for Kaminari's quirk instability after a big fight. I've seen a lot of fics where they're put on a joint patrol or work-study, forced to rely on each other in a way the main series doesn't explore. That proximity lets the tension build naturally—shared silences in the common room at 3 a.m., one making terrible coffee for the other after a nightmare. The appeal is in the quiet moments between the loud, flashy heroics.

My DenDeku reading preferences have shifted a lot, honestly. The 'coffee shop AU where Denki works as a barista and Deku is a regular trying to build confidence to ask him out' still circulates, but my favorite is a different flavor. There's a whole subgenre where Denki's quirk malfunction or overload becomes a central plot device, and Deku's analytical mind has to help stabilize him. It's less about fluffy dates and more about this intense, almost codependent dynamic built on trust during a crisis. The best one I've read had them trapped in a power grid maintenance tunnel after a villain attack, forced to rely on each other in the dark with only Denki's sporadic sparks for light. It flipped their usual energetic dynamic into something quieter and much more tense. I also really lean into the 'study buddies to lovers' trope for them. It just fits so well—Deku drowning in hero analysis notebooks, Denki struggling with theory but having incredible practical intuition. Their approaches to problems are opposite, which makes the collaboration fun to read. A lot of writers miss the potential for Denki to be surprisingly insightful about social dynamics or battle tactics in his own way, not just comic relief. When a fic gets that balance right, where Deku starts valuing Denki's input as much as All Might's, it feels incredibly rewarding. Lately I've been skipping the super popular soulmate marks or high school AUs. They can feel a bit samey after a while. Give me a post-canon, pro-hero era fic where they have to navigate public perception and agency politics together. That's where the real interesting conflict is for me.

Honestly, the nomu angle is super underused, but I've seen a few directions. One is Deku getting captured and experimented on by All For One, turning into a high-intelligence nomu while keeping his core personality locked away. The drama isn't just the body horror, but Katsuki having to confront what his childhood bullying helped create. Saw a long one that did this, but the writer dropped it after the first nomufication scene, which was a bummer. Another plot I kinda like is a reversed dynamic, where a nomu develops a weird protective fixation on Deku after a battle, maybe because of One For All's energy. It becomes this relentless, misunderstood guardian that the heroes keep trying to put down, while Deku is the only one arguing it's not purely a monster. The tension comes from whether it's just instinct or something approaching sentience.

Trying to pin down the most popular Deku and Dabi plotlines is a trip, honestly, because the pairing itself starts from such an unexpected place—hero student and villain, All Might's successor and Endeavor's eldest. The classic, almost foundational plot has to be the secret sibling reveal. Dabi is Touya Todoroki, Shoto's older brother, so a ton of fics explore him discovering Izuku is his little brother's closest friend, or that Izuku is being mentored by their father. The tension there is immense. It's not just typical enemy-to-lover; it's layered with family drama, legacy, and this horrible irony. You get fics where Dabi kidnaps Deku to get back at Endeavor, only to find this kid is nothing like their dad, and the 'caretaker' dynamic twists into something else entirely. Another massive trend is the time-travel fix-it, but with a Dabi-centric twist. Izuku goes back in time, but instead of focusing on the big heroic events, he zeroes in on saving Touya from the Sekoto Peak fire. Or sometimes it's Dabi who gets sent back, a bitter, burnt-out adult in his younger body, and he's the one who encounters a quirkless, pre-UA Izuku. These stories often sidestep the canon rivalry entirely, building a relationship on shared, hidden pain and a chance to change things. They're less about flashy battles and more about quiet, desperate alliances formed in the shadows of a past they both want to rewrite. Then you have the darker, more psychological takes—the villain Deku or double-agent arcs. Izuku, disillusioned or manipulated, joins the League, and Dabi becomes his guide or his toxic anchor. These plots thrive on moral decay and twisted devotion. They're polarizing, but incredibly popular for readers who want to explore Izuku's breaking point. The appeal isn't in redemption, but in the slow, terrifying slide, and Dabi is the perfect catalyst, mirroring his own fall from grace. You end up with stories that are less about romance and more about two damaged people enabling each other's worst impulses, which can be weirdly compelling to read, even when it makes you squirm. A lighter, though still complex, vein is the civilian or coffee shop AU, where the superhero elements are stripped back. Dabi might be a tattoo artist or a barista with severe burn scars, and Izuku is a college student or a quiet regular. The dynamic here hinges on recognizing each other's hidden depths without the masks of villain and hero. Dabi's sharp, guarded nature contrasts with Izuku's empathetic nervousness, creating a slow-burn built on small, mundane trust. It's popular because it lets their characters interact without the weight of the world on their shoulders, focusing purely on the chemistry that makes the ship work in the first place.

Honestly, the 'what if' scenario where Mirio gets to keep his quirk and becomes Deku's upperclassman mentor is everywhere, and for good reason. It lets you play with a complete power dynamic shift. Instead of Mirio having to grapple with his loss, you get this unstoppable, sunny powerhouse guiding a still-green Deku, and the potential for rivalry or a more equal partnership is huge. You can really lean into the 'Senpai-Kouhai' trope from anime that fits their characters so well. Then there's the post-'Heroes Rising' tag team idea, where they both have OFA. I've seen some writers try to navigate that shared burden and the inevitable comparison angst, but it often veers into power fantasy territory. The more interesting fics use it to explore a deep, almost psychic connection born from sharing the same quirk—like a bond nobody else can understand, which is a classic setup for intense emotional intimacy. A less common but growing niche is the 'Quirkless AU' angle for both of them, stripping away the superhero context entirely. They might meet in a support course or just a regular high school, and the story focuses on Mirio's innate leadership and Deku's analytical mind in a normal setting. It's a great way to highlight their core personalities without the plot armor of quirks, and the ship feels more grounded, sometimes even slice-of-life cozy. Of course, you can't ignore the angst potential of the canon divergence where Mirio doesn't lose his quirk but Deku still gets OFA. The guilt and 'it should have been you' complex on Deku's side, paired with Mirio's unwavering support, creates this delicious slow-burn tension. Will they compete? Will they resent each other? Or will that pressure forge something even stronger? It's a goldmine for character-driven drama.

Looking for Deku x Kota fics is tricky because it's such a specific dynamic that lives mostly in the background of bigger stories. You won't find a ton of stuff that's exclusively about them, and honestly, a lot of what's tagged feels like it's just using Kota as a convenient kid character to facilitate Izuku's hero instincts. The themes that do pop up consistently are protection and mentorship, obviously. Kota becomes Izuku's personal project post-Musselfield, with fics exploring how Izuku helps him move past his trauma and maybe even kindle a desire to be a hero himself. Sometimes Kota's quirk development gets explored as a parallel to OfA. The really popular plot ideas seem to be time skips where an older Kota enters UA as a student under Izuku, who's now a pro. Or, the much rarer but interesting take, is a role reversal where Kota becomes the emotional anchor for an Izuku struggling with the burdens of One For All. Most of it is super fluffy found family stuff, which is cute but can get repetitive. I stumbled across one once that was a weirdly compelling crossover with 'My Hero Academia: Vigilantes', where Kota, as a teen, ends up running with that crowd and Izuku has to pull him back into the light. That felt fresh because it used the established world in a new way instead of just rehashing the anime scenes. The ship itself is almost never romantic, at least in anything that's well-written; it's pure platonic or familial bonding. You have to dig through a lot of 'Dadzawa' or 'Dadmight' fics to find the good Kota & Deku content buried in subplots.

Okay, so this is actually a pairing that's super hit-or-miss for me. The most popular storyline, hands down, is the classic 'Villain Deku / Vigilante Deku' angle. Monoma gets looped in because his copy quirk is either a perfect foil or a horrifying mirror for a Izuku who's gone off the deep end. There's a lot of 'Class 1-A Betrayal' fics where Deku leaves UA after some massive injustice, and Monoma, of all people, is the one from the rival class who sees the truth and offers a hand. It's a great setup for exploring Monoma's supposed arrogance as a cover for his own insecurities, and having him recognize those same feelings in a spiraling Izuku. Another massive trope is the 'Quirkless Deku' AU, but with a twist: Monoma copies a quirk and gives it to Deku, either by accident or on purpose, sparking a whole weird dependency or partnership. It's less common than the villain arc, but it's got a dedicated following. Honestly, a lot of the fics I've clicked on end up being kinda repetitive—same angst, same betrayal plot beats. The ones that stand out are the rare fluff pieces where their rivalry just slowly melts into begrudging study sessions and then something more. Those are harder to find, but they feel like a real breath of fresh air when you stumble on them. I guess the appeal is really in the contrast—the loud, performative rival versus the quiet, determined one—and seeing how that tension bends without breaking. Makes for some interesting character studies when the writer bothers to dig deeper than the surface-level animosity.

I’ve been seeing more of these stories pop up lately, and honestly, it took me a minute to wrap my head around it. The appeal isn’t really about pairing Izuku with a literal alternate version of himself, like a clone. It’s about exploring the interior landscape of one character pushed to its absolute extreme. Think about the core of Deku’s journey: immense self-sacrifice, a fractured sense of self-worth, and this terrifying potential locked inside a body that keeps breaking. Writing 'Deku x Deku' lets authors dig into that. It’s a hyper-focused character study. You get fics where his past, self-deprecating self interacts with his future, burdened-by-responsibility self. Or fics where his analytical, fanboy side has to negotiate with the raw, One For All-powered instinct. The 'romance' or deep connection is often just a metaphor for self-acceptance or internal reconciliation. It’s popular because it bypasses all external ship drama and goes straight to the psychological meat of the character. Fans who are tired of the usual pairing wars find a weirdly satisfying purity in it. The tension comes entirely from within one person, which for a series so much about internal struggle, feels oddly fitting.
