Brian is a great character to pair with Stewie. Their dynamic in the show is already rich, and in fan fiction, it can be taken to new levels. They can have deep conversations or get into wild misadventures together.
Tommy Pickles could be the most interesting. He's the leader among the Rugrats, and in this crossover, he would be the one to try and bring the two groups together. He has a lot of courage and is always curious. When faced with Stewie's out - there ideas and inventions, Tommy would be the one to first approach and try to understand. His naivete combined with his leadership skills would make for some great story moments.
One popular theme is Stewie's adventures in different time periods. Another could be his interactions with other characters from the show in unique situations. For example, his relationship with Brian might be explored in a new light, like them going on a road trip together in a fan - made story.
Obviously, Stewie Griffin is one of the main characters. And I think his family members like Peter, Lois, Brian and the others will also be in it.
One interesting Stewie Griffin story fanfiction could be about Stewie's adventures in an alternate universe where he becomes a superhero. He could use his intelligence and his various gadgets to fight evil and protect Quahog. Another could be a story where Stewie befriends a new character who helps him understand his family better. There are also fanfictions that might explore Stewie's relationship with Brian in more depth, like a story where they go on a cross - country road trip together and have all kinds of wacky adventures along the way.
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.
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.
The show is part of the 'Family Guy' franchise, which is known for its edgy and mature - themed content. 'Stewie Griffin The Untold Story' specifically delves into some more extreme aspects of the characters and their stories, so it's definitely not made with children in mind. For kids, there are much more family - friendly animated shows available.
I don't have a definite answer for you. Stewie Griffin The Untold Story might not fit neatly into the traditional season framework.
I think a character like Leo would be great to pair with Ainsley. Leo is kind - hearted and adventurous, which can create interesting dynamics with Ainsley. Another good one could be Mia. She's smart and has a strong personality, and she and Ainsley could have some really engaging conversations and adventures together.
Bill Cipher is an obvious choice. Since they are both from the same 'universe' in Gravity Falls and seem to have some sort of connection already. Their interactions can create really interesting and often chaotic storylines.
