Which Platforms Host Popular Flowey X Papyrus Crossover Fanfiction?

Finding good Flowey x Papyrus content feels like sorting through a patch of golden flowers that bite back occasionally. The real hub for that oddly specific dynamic lives on Archive of Our Own, hands down. Tags like 'Flowey & Papyrus' or 'Asriel & Papyrus' filter better than Tumblr's wild west tagging system, and you can filter by 'Alternate Universe - Sentient Flower' or 'Post-Pacifist' to really narrow it down. AO3's collection features often gather the more experimental takes, like 'Flowey uses Papyrus's optimism to hide his own crumbling persona' stuff. I've stumbled across a few gems on FanFiction.net by searching 'Flowey Papyrus friendship' sorted by favorites, but the tone there skews toward older, more saccharine pre-Undertale fandom works. Discord servers dedicated to rare Undertale pairings sometimes have hidden Google Docs links, but it's a treasure hunt with more weeds than treasure.

I spent more time than I'd care to admit trying to track down Undyne x Papyrus crossover content, and it's definitely a deep dive. You won't find a single dedicated hub for it, as it's an incredibly niche pairing that also jumps into other worlds. Your search becomes a two-step process: first finding a platform with robust crossover archives, then using their filtering systems to sift through the chaos. I found that Archive of Our Own (AO3) is your most reliable starting point because of its meticulous tagging system. You can combine tags like 'Crossover', 'Undyne/Papyrus', and the specific fandom you're interested in, like 'My Hero Academia' or 'Harry Potter'. This precision helps cut through the mountain of other Undertale content to find those rare fusion stories. The hunt also led me to FanFiction.Net, which has a massive volume of stories but a much less intuitive filter. You'll need to navigate to the Undertale section, then the crossover category, and manually comb through summaries for any hint of the pairing—it's more of an archaeological dig. Forums like SpaceBattles or Sufficient Velocity sometimes spawn these kinds of weird, creative mash-ups in their creative writing sections, often with a more action or world-building focus. Tumblr can be a surprising source, too, with writers sometimes posting short crossovers in threaded formats, though they're harder to archive and find later. Ultimately, finding this specific content feels less like browsing a library and more like joining a very specific treasure hunt where the community itself is scattered. You get a real sense of discovery when you finally stumble on a story that mashes up 'Undertale' with something like 'One Piece' and still finds a way to make Undyne and Papyrus the core dynamic. The joy is in the strangeness of the combination itself.

I'm not super active in the 'Undertale' fandom these days, but from when I was, Archive of Our Own was overwhelmingly the main hub for that pairing, and honestly most fanfiction in general. The tagging system makes finding specific dynamics like Chara/Papyrus way easier than on older sites. I remember checking FanFiction.net out of curiosity a while back, and the tag situation was a mess; you'd have to dig through a lot of general 'Undertale' fics. Tumblr used to have a lot of snippet posts and headcanons that functioned as mini-fics, but it's harder to track down full stories there now unless you're already following the right blogs. AO3 is pretty much the only place I'd bother looking now, especially since you can filter by relationship tags and exclude other pairings you're not interested in.
