The main characters are Buffy and Faith. Buffy is a well - known slayer, strong - willed and determined. She has a lot of experience in fighting the forces of darkness.
There may also be other supporting characters in the fanfic. For example, there could be their friends or allies like Giles who might offer guidance and knowledge. Or there could be villains such as powerful vampires or demons that they have to face. But Buffy and Faith are the two main characters that the fanfic is centered around.
One idea could be Buffy and Faith having to team up to face a new type of vampire that is immune to their usual slaying methods. They'd have to rely on each other's unique skills and experiences to figure out a new way to defeat them.
For Buffy, her friends like Willow and Xander would be likely allies. Willow could use her magic to give Buffy an edge in any magical challenges, and Xander would be there for moral support and to offer his own brand of scrappy help. Giles, too, with his vast knowledge of the supernatural.
There's no way to tell without more information. If it's a fanfic related to a superhero franchise, the main characters could be the superheroes who are chosen for a new and dangerous mission. However, if it's a fanfic for a book series about a magical school, the main characters might be students who are chosen for a special competition or event. It all depends on the nature of the fanfic.
One great Buffy Faith fanfic is 'Faith's Redemption'. It delves deep into Faith's journey towards redemption. It shows how she overcomes her inner demons and tries to make amends for her past wrongs. The character development is really well - done.
One idea could be a magical competition. They compete to see who can master a new and dangerous spell first. Buffy might use her traditional training and moral compass, while Faith could be more reckless in her approach, which would create a lot of tension.
Well, clearly Chelle and Buffy are main characters. Chelle is often a new addition to the Buffy - verse, bringing her own personality and skills. Buffy, of course, is the slayer, the one who has the power and the responsibility to fight the forces of evil. There may also be other regular characters from the Buffy show like Willow and Xander who often play important roles in the fanfic as well.
Another character that might be present is Spike. His complex relationship with Buffy in the original series can be further explored in relation to the 'Daddy' concept. Whether he's an antagonist or an ally in the context of the fanfic can vary greatly, but his presence always adds an interesting dynamic to the story.
Since I haven't read this specific fanfic, it's hard to say for sure. But in a Ninjago - related 'chosen by destiny' fanfic, it could be one of the main ninja characters like Lloyd, Kai, or Zane. Maybe it's Lloyd, as he often has a central role in many Ninjago stories and could easily be a character chosen by destiny to save the day.
For Buffy, you can develop her character by exploring her doubts about her slayer duties further. Maybe she starts to question if there's a better way to protect the world than just slaying. With Faith, you could focus on her growth after redemption. She could start mentoring Devon in combat skills, which also helps her become more responsible.
Love and friendship are common themes as well. Whether it's platonic love between the two of them, or how their relationships with others are affected by their bond. In some fanfics, they learn to truly care for each other through difficult situations, which shows the power of friendship.
