Lumiere and Cogsworth are always popular. Lumiere with his charming and flamboyant personality can add a lot of humor. Cogsworth, on the other hand, with his uptight nature, creates a great contrast. Mrs. Potts is also a beloved character. Her motherly nature towards Beauty and her relationship with Chip can bring a warm family - like feeling to the fanfic.
Mrs. Potts is also a great character to include. Her motherly nature towards Belle and the Beast can be explored further. You could write about her memories from before the curse and how she tries to keep the castle in order during these difficult times. Another character could be Chip. His innocent view of the world and his eagerness to help can bring a sense of childlike wonder to the fan fiction.
There are Beauty, who is known for her goodness and her ability to see the good in others. And then there's the Beast, a character who starts off as a rather angry and lonely being because of the curse. He has the form of a beast but deep down is a prince. There may also be Beauty's family members who play a role in the story, but Beauty and the Beast are the central figures.
Goten would be a great addition. He could add some light - hearted moments and also show the family dynamic between him, Gohan and Chichi. His innocent and sometimes mischievous nature would contrast well with Gohan's more serious side.
The mother figure in the game can be an interesting character to include. Her relationship with Lucius is complex, and exploring it further in fanfiction can add depth. Another one could be the servants in the house. They often witness Lucius's actions and their reactions can be a great addition to the story.
Terra could be a great addition. He could act as a sort of mentor or a source of conflict. For example, Terra might be initially suspicious of the OC's intentions towards Ventus. Or he could be the one to encourage Ventus to pursue his feelings for the OC, seeing how happy the OC makes Ventus.
The beauty is surely one of the main characters. She is often the one who enters the world of the beasts and has to deal with their strange ways. And then there's the beast or beasts. They have their own personalities, which might be a mix of rough and kind, depending on how the story is written.
Cinderella and the Beast are often the most popular characters in such fanfics. They are the main protagonists in their respective stories, so it's natural for them to be central in the fan - created stories. Cinderella's kindness and the Beast's transformation journey are very appealing aspects that writers like to explore.
Naru is a great character to include. She has a strong connection to Ori and her backstory can be further explored. For example, you could write about her younger days in the forest. Sein is also important. You could write a story where Sein's power malfunctions and Ori has to help her regain control. And Gumo, the strange spider - like creature, can add an interesting dynamic. Maybe he has a secret that only Ori can help him with.
Snowball is a great character to include. He adds an extra layer of conflict as he also has his own ambitions for world domination. Another good one could be the lab scientists. Their presence can add some mystery and backstory to Pinky and the Brain's situation. And Elmyra, she can bring chaos as she always does in the original show, disrupting Pinky and the Brain's carefully laid plans.
