Deku X Deku Novels & Stories

Man, the deep dive into those selfcest fics always hits different. I don't know about a single 'best' archive, it's more like you've got to follow the threads through a couple of hubs. A lot of it sprouts up from 'My Hero Academia' communities on AO3, where the 'Izuku Midoriya & Izuku Midoriya' relationship tag can lead you to some mind-bending takes. Those stories often explore fractured timelines or the consequences of One For All in ways canon never touches.

I tend to avoid big, generic fanfic sites for something this specific. You get better curation from fandom-specific Tumblr blogs or Discord servers where people actually share rec lists. Someone on one of those servers once linked me to this incredibly sad, beautiful story where two Dekus from different points in time had to share a life, and it completely rewired my brain. The search feels less like browsing a library and more like asking a friend who's also deep in the weeds.

Honestly, half of what I find is through the 'works inspired by this one' link on AO3. You find one author who gets the vibe right, and then you just fall down their rabbit hole of bookmarks.

Man, the stuff where Izuku interacts with a version of himself from another timeline or a past/future self is surprisingly common. I stumbled into it by accident, looking for time-travel fics, and got hooked. It’s not just a mirror scene; it’s like a conversation you can’t have with anyone else.

The older, more seasoned Deku confronting his younger, pre-UA self forces both of them to articulate beliefs they never had to voice. The younger one sees the hero he could become, flaws and all, which is terrifying and motivating. The older one has to face his own naivete and remember why he started. It cuts through all the external validation—All Might’s approval, class rankings—and makes the growth entirely internal. The conflict becomes about reconciling your own ideals with your own lived experience.

I read one where future Deku was jaded from losses, and present Izuku basically re-convinced him of their shared core principle: saving people with a smile. That hit hard because it wasn’t an outside force renewing his hope; it was literally himself.

I've seen a few different approaches to this, and they all hinge on how you interpret the concept. Some writers lean into the multiverse angle, with different Midoriyas from divergent timelines meeting. That can get pretty philosophical, fast—what does it mean to meet yourself? Are you jealous of the version that got a quirk earlier, or pity the one who suffered more? The conflict is all internal, which is tough to write well.

Another take is the clone or duplicate scenario, often from a villain attack or support item malfunction. That one's usually more about practical problems and emotional doubling. Does he feel twice the guilt, twice the responsibility? I read one where the two Dekus had to decide which one got to keep the 'real' life, and it was heartbreaking because they both wanted the other to have it. The self-sacrifice instinct turned inward.

Then there's the metaphorical or psychological version, where it's less literal and more about Izuku confronting his own self-image, his shadow self, or his past/future self through visions or mental landscapes. Those can be super introspective and quiet, almost like a character study dressed up as a supernatural encounter. The relationship isn't romantic in a traditional sense, but it's deeply intimate because it's literally with himself.

Honestly, I'm less convinced by the straight-up romantic pairings of two identical Dekus—it feels like it misses the point. The interest for me is in the duality and the internal dialogue, not just creating a mirror for shipping purposes. The best fics use the setup to explore his character fractures.
