Jodie and Aiden together are a great focus. Their bond is so special and a fanfic could show more of their interactions outside of the main story. Then there's Zoe, who could be a central character in a fanfic that explores the scientific side of Jodie's powers. Maybe Zoe is trying to find a way to replicate Jodie's abilities in a more controlled way. And Jay, Jodie's foster brother. A fanfic about their relationship growing up and how it was affected by Jodie's powers could be really touching.
Nathan Dawkins is also quite popular in Beyond Two Souls fanfiction. He has a complex role in the game and there is a lot of room to expand on his character, his motives, and his relationship with Jodie. Also, Cole Freeman can be a great character to feature. He has his own story arc in the game and fanfiction can explore different aspects of his personality and his interactions with other characters.
In a crossover with the X - Men universe, characters like Professor Xavier would be great. He could try to understand Jodie's powers and perhaps help her control them better. Wolverine could also be included as he has his own experience with being different and having special abilities. He might team up with Jodie for a mission. Another good character would be Storm. Her control over the weather could create interesting interactions with Jodie's psychic powers.
Philip and Elizabeth Jennings are obvious choices. Their complex relationship and double lives are full of potential for fanfic exploration. You can create scenarios that further test their loyalty to each other and to their country.
Jack is a great character to focus on. He's the main character, so there's a lot of material to work with. His growth in martial arts and his relationships with the other characters are rich areas to explore. For example, you could write about his struggle to master a new move and how his friends help him.
I think focusing on the Wattersons family as a whole can be really interesting in a Gumball fanfic. You can show their family dynamics, like how Richard's laziness affects the household, or how Nicole's strictness is both a help and a hindrance. Then there are the friends like Carrie, the ghost girl. Her spooky nature and her friendship with Gumball and the others can add a unique element to the story. And Tobias, with his one - sided crush on Penny, can also bring in some elements of unrequited love and jealousy into the fanfic.
One idea could be exploring Jodie's life after the events of the game. Maybe she tries to use her powers for more mundane things like helping in disaster relief efforts around the world. Another could be a prequel fanfic that delves into her childhood and how she first discovered and learned to control her powers. Or perhaps a fanfic where she meets other characters with psychic abilities and they form a sort of 'supernatural team' to take on threats that the normal world can't handle.
To develop their relationship, you could start with small moments of trust - building. For instance, Jodie could share a small part of her power's downside with Jay, and Jay could respond with understanding and support. This would create a deeper bond between them.
Austin and Ally are the main characters, so they should be at the center. However, Dez can't be ignored. His wacky ideas for Austin's music videos and his general goofiness can create some hilarious scenarios in a fanfic. You could also explore more of the relationship between Dez and Trish, which is often overlooked in the show.
Jack Frost is a very popular choice. His mysterious past and his cool powers make him an interesting character to explore. You can dig into his feelings of isolation before becoming a Guardian and how he's changed since then.
Fat Amy is a great character to focus on. Her larger - than - life personality and unique sense of humor can bring a lot of fun to a fanfic. You could write about her secret talents or her family back in Australia.
