Madame Giry can be an interesting character to focus on as well. She has a connection to the Phantom and could be used to explore the backstory of the Phantom and the opera house in a different way in fanfiction. For example, a fanfic could explore her own past relationship with the Phantom or her role in protecting him.
Obviously, Christine and the Phantom are the most popular. Christine is the object of the Phantom's affection and her own journey of self - discovery, torn between her feelings for Raoul and her strange connection to the Phantom, is fascinating. The Phantom himself, with his tragic past and his complex personality, is also a great focus. His talent for music and his dark side make him a very interesting character to explore.
Obviously, Christine and the Phantom are the most popular. Their complex relationship, with the Phantom's obsessive love and Christine's mix of fear and fascination, offers a lot of room for exploration. Raoul can also be a key character. He represents the 'normal' love interest for Christine, and his presence can create a lot of tension when pitted against the Phantom's more extreme passion.
Christine is also a central figure. Fanfiction can explore her feelings for the Phantom and Raoul in more depth. Maybe she has a secret side that she hides from both of them, or she could be given more agency in the story, rather than just being the object of the men's affections.

She has an interesting role in the story, and her loyalty to the opera house and her friendship with Christine can be delved into in fanfiction.
Sam and Tucker are really interesting characters to focus on. Sam's gothic personality and her strong beliefs can lead to some great storylines. Tucker's tech - savvy nature can be used in many ways, like developing new gadgets or helping Danny figure out some tech - related mysteries. And Jazz, Danny's sister, with her psychology knowledge could play a crucial role in understanding Danny's situation better in a fanfiction.
Raoul is Christine's childhood friend and later her suitor. He represents safety and normalcy compared to the Phantom. His love for Christine is pure, but he may not understand her as deeply as the Phantom does in some aspects of the story.
Obviously, Danny and Dan themselves are very popular. Danny as the main hero and Dan as his dark and complex counterpart are central to many stories. Jazz, Danny's sister, is also popular as she can provide a different perspective and often gets involved in Danny's ghost - fighting adventures in fanfiction.
Andy Herrera is often a popular choice. Her strong leadership skills and complex family background make for great fanfiction material. Writers can explore her relationship with her father, Pruitt, and how she balances her personal and professional life.
Hannibal is often a popular focus. His leadership skills and strategic mind make for great storylines. Writers can explore his past military experiences in more detail or create scenarios where he has to outwit an even smarter adversary.
Well, the phantom stallion itself is obviously very popular. It's the centerpiece of the fanfiction. People are drawn to its wild and mysterious nature.
