Nami is also quite popular. In fan novels, she might be given more complex roles in navigation or even in combat. For example, some fan stories could focus on her developing new skills related to weather control, which is related to her original role as the navigator but takes it to a new level.
Luffy is still extremely popular in fan novels. His carefree yet determined nature makes him a central figure in many fan - created stories. Writers often put him in new and exciting adventures that build on his character traits from the original series.
Law is another character that often shows up in fan novels. His unique Devil Fruit power and his mysterious past make him a great subject for fan - created stories. Writers might explore his relationships with other characters more deeply, or put him in situations where he has to use his powers in creative ways that we haven't seen in the original One Piece series.
