Sigmar is a very interesting character. He was a great leader and his legend has a huge impact on the world of Warhammer Fantasy. Writing about his early days as a warrior or how his legend influenced future generations can be really engaging.
The Sole Survivor is a very interesting character to write about. Their backstory of losing their family and then emerging into the post - apocalyptic world gives a lot of room for character development. Codsworth, the friendly Mr. Handy, can also be interesting. You can write about his loyalty to the Sole Survivor and his unique perspective on the world. Another is Nick Valentine. His synth nature and detective skills make for great storylines, especially when he's solving mysteries in the wasteland.
Well, it really depends on the writer's preference. But if we consider the main characters, Van Pelt has a lot of potential. Her journey from a newbie in the team to a more experienced agent can be explored in many ways. Her relationship with Rigsby, and how she balances her personal and professional life. Another interesting character is the psychic that Jane sometimes consults. There's a lot of mystery around that character, and fan fictions can expand on his abilities, his relationship with Jane, and how he fits into the overall world of The Mentalist.
I think the antagonists in 'the gifted fan fiction' can be really interesting to write about. They often have complex motives for their actions. Maybe they are using their powers for a cause they believe in, but that goes against the heroes' values. Their backstories and how they came to be the way they are can add depth to the fan fiction. Also, the side characters with more subtle powers can be great to write about as they can surprise readers with their abilities in unexpected situations.
Mal is definitely one of the most interesting. She has such a complex personality, being the daughter of Maleficent. There's a lot to explore in terms of her struggle between her mother's dark legacy and her own desire to be good. Evie is also great. Her journey from being a'spoiled' princess - type to someone more independent and kind - hearted can be really fun to write about. And then there's Jay, with his thieving ways but also his potential for growth and loyalty.
Chuck himself is very interesting to write about. His transformation from a regular guy to a spy is full of potential for different storylines. Sarah is also great. Her mysterious past and her relationship with Chuck can be explored in many ways.
Clark Kent is obviously one of the most interesting. He has so many layers to his character, from the shy farm boy to the emerging superhero. His internal struggles with his powers and his moral compass make for great writing. Lex Luthor is another. His complex personality, with his intelligence and his slow descent into darkness, gives a lot of room for creative interpretations in fan fiction.
Definitely Edward. His complex nature as a vampire who is trying to resist his baser instincts while being in love with a human makes for great material. Writers can explore his internal struggles in more depth. Also, his past and how he became a vampire can be elaborated on in fan fiction.
The Space Marines are really interesting. They are genetically enhanced super - soldiers with a strict code of honor. You can explore their internal struggles between loyalty to the Emperor and their own sense of self. Another interesting character is the Inquisitor. They have a lot of power and mystery, investigating heresy and xenos threats. And the Eldar Farseers are cool too. Their psychic abilities and knowledge of the future can lead to some really complex and engaging storylines.
Well, I think Mr. Bun, Calvin's stuffed bunny, could be an interesting character in fan fiction. There could be stories about his 'life' when Calvin isn't around. And Rosalyn, the babysitter, is also a great character to write about. Her battles with Calvin are classic, and fan fiction could expand on those moments. But overall, Calvin and Hobbes remain the central and most fascinating characters, as their relationship is the heart of so many possible stories.
Perry Mason himself is of course a very interesting character to write about. His intelligence, charm, and ability to outwit his opponents in the courtroom offer a lot of material. Della Street, his secretary, is also a great character. Her loyalty and her role in helping Perry Mason with his cases can be explored in fan fiction.
