What Are Common Plot Themes In Venom Crossover Fanfiction Crossovers?

Can't believe no one's mentioned the 'Eddie/Venom symbiote as a third entity in the relationship' thing yet. It feels like half the fics I stumble across have that setup—Eddie's talking to both the symbiote and another person, dealing with a weird love triangle where one corner is an alien goo creature. The dynamics get so messy and fun. Lots of writers go for the 'Venom secretly pining while Eddie's oblivious' angle, which works surprisingly well for hurt/comfort. And the Venom/Spider-Man rivalry-to-lovers tag is still overflowing. It's a specific vibe—less about the MCU 'Venom' movies and more pulling from older comics or the '90s cartoon. You get that push-and-pull where they're trying to kill each other one minute and making out the next. I kinda prefer when the symbiote's influence is a source of conflict instead of just, like, sexy window dressing. Surprisingly common pairing I never expected: Venom/Carnage. Yeah. It's out there. Usually super dark, often non-con, tons of body horror. I steer clear but the tags pop up constantly in certain corners of AO3.

I think the most obvious one is the struggle over Eddie’s body and agency. Like, Venom wants to eat people, Eddie’s got this whole moral compass thing going on, and that creates this constant, gnawing tension. It’s not just about good vs. evil, though. It’s about consent and partnership. Is Eddie hosting Venom or are they co-piloting? A lot of fics dig into that power imbalance, especially when they’re still figuring each other out. The fear of losing yourself is huge. Another big theme is the weird intimacy of their bond. They’re literally sharing a mind and body, which is more intense than any romantic relationship. Writers love playing with that—the jealousy when Eddie pays attention to someone else, the vulnerability of being completely known, the horror and comfort of never being alone. It’s a messed-up codependency that can swing from deeply tender to terrifyingly toxic in a paragraph. That emotional whiplash is catnip for fic authors. Then there’s the external conflict of being hunted or feared. How do you build a life when you’re a walking public menace? The loneliness of that, except you’re not even lonely because you’ve got an alien in your head commenting on everything. Fics that focus on them trying to be ‘normal’—getting coffee, dating, holding a job—always highlight that underlying panic and absurdity. The emotional conflict isn’t always grand; sometimes it’s just the exhausting, daily stress of being different.
