I think Otto is a prime character for Time Squad fanfiction. He's young and still learning, so there's a lot of room for character development. You can write about his challenges and how he overcomes them. Buck is another excellent option. His no - nonsense attitude and his knowledge of different time periods can be the basis for many exciting adventures. Sally, too, with her intelligence and ability to handle difficult situations, can be a central character in a great fanfiction.
In Time Squad fanfiction, Otto stands out as a character to focus on. His inquisitive nature and his relationship with the other members of the team can be delved into deeply. Buck, as the leader, has a wealth of experiences that can be explored. His decisions and how they impact the team can be a great plot point. Larry, with his love for food and his somewhat clumsy nature, can also be a fun character to base a fanfiction around. He can provide the comical relief while still being an important part of the team.
Otto and Olive are great characters to focus on. They are the main characters in the show and have a lot of interesting adventures. Their friendship and how they solve problems together can be explored in fanfiction.
Sirius Black is a great character to focus on. His rebellious nature can lead to some really interesting time - travel scenarios. For example, he might be the one to break the rules of time travel and cause some chaos.
The main family members can be great to focus on. Their relationships, power struggles, and dreams offer a lot of material. For example, the patriarch of the family who has to make tough decisions to keep the ranch going. Another good character could be the strong - willed matriarch who holds the family together. Also, the young and rebellious heir who wants to do things his own way.
Sersi is a great character to focus on. She has a strong connection to humanity and her powers are quite interesting. You could explore her relationships with humans in more detail. Another good one is Ikaris. His loyalty and the internal conflict he might face are good material for a fanfiction. Then there's Kingo, with his love for movies and his unique charm among the Eternals.
All of the members of 4 town are great to focus on in different ways. Tae Young, for example, might be the subject of a fanfiction where his amazing dancing skills are the center of the story. Maybe he gets an offer to be in a big dance competition outside of the band, and he has to decide whether to take it or stay loyal to 4 town. Each member brings their own unique traits that can be explored in fanfiction.
The friends of the main couple can also be great to focus on. They can add humor, support, or even create some conflict. For example, a friend who is always teasing the couple about their relationship can be a fun addition to the fanfiction.
Sebastian is a fun character to focus on. You can write about his loyalty to Ariel and how he tries to keep her out of trouble. He could have his own mini - adventures in a fanfiction, like getting lost in the human world while trying to find Ariel. Flounder is another good one. You could show his growth from a timid fish to a more brave friend of Ariel's. Also, Triton, Ariel's father, can be a central character. You can explore his relationship with Ariel in more detail, like his struggle to let her go.
In my opinion, Magnus Bane could be a great character to focus on in Clockwork Angel fanfiction. He has such a flamboyant personality and his magic abilities are quite interesting. He could interact with the main characters in ways that haven't been explored in the original story. Another good character would be Charlotte. As the head of the Institute, she has a lot of responsibilities and secrets that could be delved into. And of course, Tessa. She is the center of the story in many ways, and her character development is something that can be further explored in fanfiction.
Obviously, Bella herself is a great character to focus on. She's the main character and has so much potential for different storylines. You could explore her growth as a football player and as a person.
Well, Danger is a character that can be really interesting in fanfiction. His backstory as an ordinary kid turned superhero can be delved into more. Maybe he has some hidden powers that he discovers during a really tough mission. Another great character is Trent, the bully - turned - helper. You can write about how he fully integrates into the Danger Force's world and how his past experiences as a bully shape his new role as a hero - in - training. And of course, the villains in Danger Force can also be great focuses. For instance, writing from the perspective of a villain who has a change of heart and tries to join the good side can be a really engaging story.
