Cara Dune could be included. For example, she and the Mandalorian are on a mission to stop a crime syndicate that is causing trouble in the Outer Rim. It would be a story full of action and their unique friendship dynamic.
Grogu is an obvious choice. You can write about his further training in the ways of the Force. Maybe he starts to show some unexpected powers that even the Mandalorian is surprised by.
In Knight Rider fan fiction, aside from the obvious Michael Knight and KITT, characters like Tanya Walker can be really interesting to include. She was a journalist who got involved in some of the adventures. Captain Darien Lambert from the 'Team Knight Rider' spinoff could also be incorporated for a different take on the Knight Rider universe. And then there's Russell Maddock, a technician who could provide some behind - the - scenes knowledge and add a bit of humor to the story.
Obviously, Scooby Doo himself is a must - include. Shaggy is also very popular as his sidekick. Fred, with his trap - making skills, is another great character. And Velma, with her brains, always adds depth to the story. Daphne can also be included for her charm and occasional moments of bravery.
The babysitter herself is an obvious choice. She can be the main character who drives the story forward. The kids she babysits are also important characters. Each kid can have their own unique personality, like one could be really adventurous, another could be shy but curious. And don't forget about the parents. They can be involved in the story too, for example, they could call in the middle of an adventure with some important news or request.
The star quarterback of the football team would be a popular character. He's the hero on the field, but off the field, he has his own insecurities. Another could be the head of the school newspaper, a smart and curious student who is always digging for the next big story. And the strict but fair principal, who has to deal with all kinds of problems at the school.
Obviously, Dr. John Watson. Even as a young boy, he can be Sherlock's sidekick, providing a different perspective. He might be more emotional and less logical than Sherlock at first, but he learns from him.
In 'Shokugeki no Soma' fan fiction, aside from Soma, Megumi is a beloved character to include. Her growth throughout the series and her kind nature can bring a different dynamic to a story. Ryo Kurokiba is also a popular choice. His wild and aggressive cooking style, along with his loyalty to his mentor, can add an exciting element. And of course, Isami Aldini, Takumi's brother. His support for Takumi and his own cooking skills are great for creating interesting relationships and plotlines in fan fictions.
Evan himself is obviously a key character. His journey with the divine powers is the central part of the story, so he's always a must - include.
In Disney Seabrook fan fiction, Zed and Addison are really popular. Their love story is a central part of the Seabrook story, so fans love to expand on it. Another character is Eliza, the smart zombie. She can bring in elements of mystery and problem - solving. Also, the werewolves, like Wyatt, are popular. Their wild nature and their own community within Seabrook can create interesting storylines, especially when they interact with the zombies and humans.
A new detective in their department could be a great character. This detective could be young and eager, but also a bit of a rival to Rozzoli. He might have different methods of solving cases and could create some tension in the team. At the same time, he could also develop a friendship with Isles, which might make Rozzoli a bit jealous.
Obviously Clifford himself is a must - include. He's the star of the show. Emily Elizabeth is also very popular as she is Clifford's human best friend. Cleo and T - Bone, Clifford's dog friends, are often included too as they add more animal - related storylines and interactions.
