Where Can I Find Crossover Sonic The Hedgehog Fanfiction With Other Games?

The crossover scene for Sonic is surprisingly robust if you know where to look, but it's definitely scattered. I've spent way too many hours hunting for good fics, so let me save you some trouble. Archive of Our Own is the current powerhouse, no question. The tagging system is a godsend for finding specific crossovers—you can filter for fandoms like 'Super Mario', 'Pokémon', or 'Marvel Cinematic Universe' and combine it with Sonic tags. The quality there tends to be higher on average, with more complete stories and authors who understand both source materials. I stumbled on this fantastic, long-running 'Sonic & My Hero Academia' fic there that completely recontextualizes Sonic's speed in a world of quirks. Don't sleep on FanFiction.Net either, despite its age. The sheer volume is immense, and for older or more obscure crossovers—think 'Sonic & Digimon' or 'Sonic & Star Fox'—it's often your only bet. The search is clunky, but sorting by favorites or reviews can surface the classics. Just be prepared to wade through a lot of... let's call it 'early 2000s enthusiasm'. I found a genuinely epic 'Sonic the Hedgehog/Kingdom Hearts' saga there years ago that I still reread, full of that melodramatic charm the site is known for. Smaller, dedicated forums are the wild west. Sites like SpaceBattles or Sufficient Velocity have creative writing sections where users pit universes against each other in often shockingly detailed ways. You'll find debates on power scaling between Sonic and Goku bleeding into full-blown narratives. The tone is different—less about shipping, more about hypothetical clashes and world-building logic. It's a specific vibe, but when it hits, it's incredibly satisfying for a certain kind of fan.
