What Are The Top Stewie X Brian Fanfiction Stories To Read?

Honestly? I think the fandom kind of peaked a few years back. The really good longfics are either complete or abandoned. Check out 'Ego and Id' on FFN—it's a crossover with 'Dexter' of all things, and it shouldn't work but somehow does. Stewie sees Dexter Morgan as a kindred spirit, and Brian has to play the hapless moral compass trying to rein them both in. It's unhinged in the best way possible and weirdly in-character.

Most people default to AO3, which is fair—the tagging system makes it easier to avoid the weird stuff. But honestly, a lot of the absolute classics for this pairing are still buried on older forums like FanFiction.net. They don’t get re-uploaded because the authors have moved on. The thing is, the show’s humor is so referential and meta that fanfics from its peak seasons (like when Brian and Stewie were paired together constantly) have this specific energy that newer writers don’t always capture.

My personal favorite has always been 'Roads Not Taken' by Teratornis. It’s archived on a few personal sites still. It’s a time-travel fix-it where Stewie tries to prevent Brian from getting hit by the car in that one episode, but every change he makes just makes things worse in absurdly darkly funny ways. It nails Brian’s voice—the self-loathing wrapped in pseudo-intellectualism—and Stewie’s frustration at being the only one who remembers the original timeline. It’s less laugh-out-loud and more of a slow, comedic tragedy about two deeply flawed characters who can’t stand each other but also can’t function alone.

Searching for it is half the battle. Sometimes you find these old Geocities-era pages with terrible formatting, but the writing itself is sharp.

Brian’s the one who’s actually written a couple books, right? And Stewie’s the narcissistic genius with the constant murder plots. You put them in the same room, and you’ve got this bizarre, weirdly functional dynamic where they’re both smart enough to keep up with each other’s nonsense. The best stories lean into that. They’re not just about the banter, though the banter’s usually fantastic. They take the genuinely good moments from the show, like when Stewie helps Brian with his writing or when they travel in the time machine, and build a whole story around that shared history.

It’s a bit like buddy cop stuff but with a talking dog and a baby. The tone varies wildly—some are dark comedies where Stewie actually succeeds with one of his schemes and Brian has to clean it up, others are surprisingly introspective one-shots after a bad night for Brian. 'The Fine Art of Mutual Destruction' is still the gold standard for me. It starts with them trying to ruin Lois’s dinner party for petty reasons and escalates into them having a real argument about why they even hang out. The way it weaves in Stewie’s hidden vulnerability about being truly understood and Brian’s fear of becoming irrelevant is way deeper than 'Family Guy' ever goes.

A lot of the newer stuff on AO3 has been playing with the ‘what if they had to move in together after Brian got kicked out again’ premise, and it leads to some hilarious domestic chaos. Just avoid anything that tries to make it seriously romantic—that just feels weird and misses the point. The platonic soulmate angle is where all the good material lives.
