Okay, so symbiote fanfic is a surprisingly deep well once you start digging. Most of it is, obviously, attached to specific canons like 'Spider-Man' or 'Venom', so you find the big hubs for those. AO3 is absolutely packed with symbiote-centric stuff, especially if you're into the more complex host-bond dynamics, whump, or outright horror. The tagging system there is a lifesaver for finding stories focused on characters like Eddie Brock, Venom, or even original symbiote characters.
I've also seen a decent amount on FanFiction.net, though sorting through the older archives can be hit-or-miss—lots of classic fics from the early 2000s Raimi movie era are still kicking around there. For more niche, original symbiote stories that aren't tied to Marvel, your best bet might be smaller, forum-based creative writing communities or sites like SpaceBattles or Sufficient Velocity, where people sometimes cook up entirely original universes with symbiotic lifeforms as a core concept. Those can get really creative with the rules of bonding.
The real treasure trove, though, is in the crossovers. Searching for symbiote fusions on AO3 can pull up wild stuff like Venom bonding with characters from 'My Hero Academia' or 'Teen Titans', which often ends up being a fresh take on the whole premise. Tumblr and Discord servers dedicated to symbiote art and fic are also great for finding links to independently hosted stories or Google Docs that don't live on the big archives.

Venom and 'My Hero Academia' characters make for a shockingly good mashup. You see symbiotes latch onto someone like Midoriya, and suddenly the story isn't just about power, it's about that internal struggle between his innate heroism and the symbiote's primal hunger. Shinsou with a voice in his head that actively tries to corrupt his goals? That's a character study waiting to happen. Then you have the over-the-top fun of Venom bonding with someone like Katsuki Bakugo—imagine the sheer chaotic energy of two aggressive, prideful beings trying to dominate each other. It's less about horror and more about explosive personality clashes, which can be a hilarious read.
Crossing over with 'The Magnus Archives' opens a different kind of door. A symbiote isn't just an alien; it becomes an entity of The Flesh or The Slaughter, feeding on fear and trauma in a world already drowning in it. The horror becomes psychological, the bond a source of creeping dread rather than superheroics. I've seen a few where Jon Sims starts hearing another voice in his head during his tenure as Archivist, and the slow unraveling is masterfully unsettling. It's a niche within a niche, but the tonal match is uncanny.

Honestly, AO3 is the undisputed champion for this specific niche. Their tagging system is a lifesaver when you're hunting down something as specific as Venom crossovers. You can filter by fandom and relationship so easily, and the sheer volume of work there dwarfs everywhere else. I've found some truly bizarre but brilliant crossovers there, like Venom bonding with a character from 'The Magnus Archives' or infiltrating the 'My Hero Academia' universe. The writers on AO3 also tend to lean into the weird body horror and odd couple dynamics that make Venom so fun in the first place.
FF.net has some older gems, especially from around the 2018 movie boom, but sifting through it is a chore. Wattpad has a younger vibe and a lot of self-insert stuff, which can be hit or miss depending on your taste. For me, the depth and discoverability on AO3 make it the only place I bother checking anymore.

Honestly, my brain goes straight to ‘Symbiote’ by Closet7Adventurer on AO3. It’s an older Peter Parker story that’s still getting updates, weirdly enough. The conflict isn’t just ‘venom makes him angry’—it’s about the symbiote as a reflection of his own buried grief and guilt after 'No Way Home'. The layers come from Peter trying to use the symbiote’s power to fix things, to literally rebuild a life, while it feeds on that desperate, nostalgic sadness. You get this slow corruption that feels justified, almost logical, because the host’s starting point is so broken.
What makes it stand out is the lack of a clear villain. The symbiote isn’t evil; it’s an addict and Peter is its drug. The external conflict with other heroes feels secondary to the internal negotiation between two damaged beings trying to use each other to feel whole. It gets messy in the best way—the morality is murky, and the line between protector and parasite blurs until you’re not sure who’s saving whom. Some of the prose gets a little purple, but the core dynamic is painfully human, even when neither participant technically is.
