Is It Fair Use?

Character and Purpose: Derivative

In general, it is not Fair Use to make fanfics, fanart, or any other fan-made work that uses the characters and/or settings of the original. However, some creators are more accepting of fan works as long as the fans follow certain limitations. For instance, earning money is generally not permitted, and many creators of children's media do not permit their characters in adult settings.
