Well, in addition to Billy and El, other characters from the original series could also be important. For instance, Mike could be involved as El's friend. His relationship with El might cause some tension between him and Billy. Also, Joyce, as a mother figure, could play a role in bringing Billy and El closer together as a family.
Billy and El are the central figures. However, Billy's friends or El's other friends from the lab might also be part of the story. Billy's friends could initially be against El, thinking she's strange, but as they see the bond between Billy and El grow, they might change their minds. And El's lab friends could offer some insights into her past and help Billy understand her better.
The main characters would obviously be Billy and El. Billy, who has his own complex personality, and El with her unique powers.
One possible plot could be that Billy, being El's brother, discovers her powers and tries to protect her from the people who want to use her for their own gain. He might use his own street - smart skills to keep her safe in the real world while she tries to control her powers.
Well, obviously Billy and Mandy are the main characters. Billy is often the goofy and naive one, while Mandy is more cynical and in control.
Well, clearly the main characters are Billy Joe Cobra and Spencer. Billy Joe Cobra might be a character with a lot of bravado and charm. He could be the type who is always looking for the next big adventure or opportunity. Spencer, on the other hand, could be more of a thinker, someone who plans things out carefully. In the fanfic, their different personalities would interact and drive the story forward.
Not having read the 'el dorado novel', it's difficult to determine the main characters. But if it's set in the context of the el dorado legend, it may have a group of adventurers as main characters. These adventurers could come from different backgrounds, perhaps a young and ambitious archaeologist, a grizzled old sailor with tales of far - off lands, and a local native who has some knowledge of the el dorado legend. They would each bring their own motives, skills, and personalities to the story, and their interactions and relationships would drive the plot forward as they search for the elusive el dorado.
If it's set in a school or work environment, Bella's friends or colleagues could be main characters. They might notice the changes in Bella as she discovers this new family connection. Also, if there are antagonists in the story, it could be someone who doesn't want Bella and Billy to form a relationship. This could be someone who has a grudge against Billy and sees Bella as a way to get to him, or it could be someone who is jealous of Bella getting a new family.
Based on the title, it seems that the main characters are Mom and Billy. Since the story has something to do with 'Billy's balls', Billy is clearly an important part, and Mom is also involved, perhaps in a relationship to Billy's situation regarding the balls.
The main characters are obviously Aro and Baldo. Aro is likely to be a significant figure, perhaps with certain status or power. Baldo, as his half - brother, will be another central character, with his own story arc related to Aro.
In RWBY Little Brother Fanfic, aside from the RWBY girls, there could be other characters who are important in the little brother's life. For instance, there might be a mentor figure who helps the little brother develop his skills. This could be an older Huntsman or Huntress who has a lot of experience in the field. There may also be antagonists who specifically target the little brother because of his relationship with the RWBY team or his own unique abilities. These antagonists can create conflict and drive the story forward, making them also key characters in the fanfic.
Another possible character could be Kakashi. As their sensei, he could train Naruto and Souna together. He would guide them in developing their ninja skills and also give them advice on how to deal with the challenges they face as brothers. Kakashi's wisdom and experience would be crucial in their growth, and his presence could add more depth to the story, especially when it comes to the relationship between Naruto and Souna.
Well, clearly Sakura and her brother are the main characters. Sakura is likely to be a character with her own unique traits, maybe she's kind - hearted or has a special talent. Her brother, on the other hand, might be more of a protector type, strong and reliable.
