Spiderman Fanfiction

AO3's my usual haunt for that kind of thing. The tagging system is a lifesaver—you can filter for 'Crossover' and then add 'Peter Parker & Other Superheroes' or whatever dynamic you're craving. I've found some wild, fun stuff blending Spidey with the 'Daredevil' Netflix vibe, or even hopping over to Gotham. Sometimes the best finds are in the 'Marvel Cinematic Universe' fandom tag rather than a specific 'Spider-Man' one, because writers will just tag all the characters featured.

Honestly, Tumblr's a mess for actual reading, but it's weirdly good for discovery. Writers will promo their multichapter crossovers there with moodboards, and you can follow a trail of reblogs to the actual story posted on AO3 or FanFiction.net. The latter site has a ton of older material, like pre-MCU crossovers with the 'X-Men' movies or even the Raimi trilogy meeting other heroes. The search function is clunky, but the sheer volume means there's gold if you're patient.

Don't sleep on niche forums or dedicated Discord servers either, especially for specific pairings like Spider-Man/Iron Man team-ups. The rec lists there are curated by superfans who've already sifted through the mediocre stuff. My to-read list is mostly from those kinds of places, stuff I'd never have stumbled on with a basic tag search.
