Well, it could also be a very emotional and character - study type of fanfiction. Thor chokes Tony not really out of hatred but out of deep - seated fear. He might be afraid that Tony's actions will lead to the destruction of everything they hold dear. And this act of choking is more like a wake - up call for Tony to realize the gravity of the situation.
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.
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.
Stewie's quotes are very distinctive. If in a novel, they might be used to characterize a particular type of character, perhaps one with a mischievous or overly - intelligent streak. His quotes can also be a source of satire, making fun of certain social or family dynamics, which could be effectively utilized in a novel's plot or sub - plot.
Yes, there might be some fan - made or even official novels related to 'Family Guy' that could feature Stewie. However, I'm not entirely sure if there's a dedicated one just about him. You could check official 'Family Guy' merchandise websites or big book retailers.
It's hard to say if it's extremely popular in a general sense. Among certain subsets of 'Family Guy' fans who are interested in exploring different interpretations of the characters, it might have some popularity. But compared to more mainstream 'Family Guy' - related content, it's likely a niche area.
Cap might be the one to stop Thor. He is known for his sense of justice and leadership. He would step in between them and try to calm Thor down, reminding him that they are all on the same side and that violence is not the solution.
Fanfic involving Brian and Stewie in inappropriate or sexual situations is not appropriate at all. 'Family Guy' is a show mainly aimed at comedic and family - related entertainment. Such inappropriate fanfic goes against the general spirit of the show and is also not suitable for a wide audience.
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.
