What is fan fiction definition?

Fan fiction refers to stories or books that are written by fans of a particular fictional universe or story. These works of fiction are created using the characters, setting, and plot of the original work, but with an added twist or spin on it. The purpose of fan fiction is often to explore what happens after the original story ends. Fan fiction can be found online, in fanzines, and even in published novels. It is often controversial, as it can be seen as copyright infringement, and because it can sometimes involve graphic or adult content that is not suitable for all audiences. While fan fiction can be a fun and creative outlet for fans, it is important to respect the original author's intent and not make money from their work.
