One common theme is friendship. Despite their differences, Brian and Stewie often form a strong bond in fanfics. Another theme is adventure, like going on wild trips around Quahog or even to other fictional places.
Family also pops up as a theme. Since they are part of the same family in the show, fanfics may explore how their relationship affects the family dynamic. For example, how they deal with other family members' reactions to their strange antics. And of course, humor is a big theme. Their contrasting personalities - Brian's more laid - back and Stewie's over - the - top - create lots of comical situations in the fanfics.
One common theme might be the unique bond between Brian and Stewie. Since they have such a complex relationship in the show, fanfic writers might explore that in a different light.
One common theme is friendship. Despite their differences, Stewie and Brian are often depicted as having a deep bond in fanfiction. Another theme is adventure. They might go on wild trips or face strange challenges together.
They could be in an adventure together. For example, Stewie and Brian could go on a journey through time, using Stewie's wacky inventions. This would be in line with their characters' personalities as Stewie is always creating strange things and Brian is often dragged into his schemes.
One possible theme could be friendship taken to an extreme or misinterpreted moment. Maybe there's a situation where they are under some sort of magical or comical influence that leads to the kiss, and then they have to deal with the aftermath in terms of their relationship.
No. 'Stewie and Brian' are characters from a family - oriented show. Writing sexual fanfic about them is inappropriate as it goes against the family - friendly nature of the original source and can be considered a form of inappropriate and unethical use of the characters.
One idea could be a story where Brian and Stewie go on an adventure in outer space. They could encounter strange alien species and have to use their wits to get back home.
One aspect that makes Brian x Stewie fanfic interesting is the unique dynamic between the two characters. Brian, the intellectual dog, and Stewie, the baby genius with a devious side, create a lot of room for creative and often humorous interactions in fanfiction.
Since the show 'Family Guy' has a large cast of characters, it's likely that the novel would also include some of the supporting characters. Quagmire could show up and add his perverted sense of humor to the mix. And Meg could be there, with her awkward teen - age experiences, which could contrast with Stewie and Brian's more out - there adventures.
I'm not really into that genre, but you can try searching on some popular fanfic websites like Archive of Our Own. There might be a few there.
A great fanfic is 'The Mysterious Case with Brian and Stewie'. In this story, they team up to solve a mystery in their neighborhood. The fanfic is full of suspense and humor as they follow clues, interview neighbors (with Stewie's hilariously inappropriate questions), and ultimately solve the mystery in a very Brian - and - Stewie - esque way.
