Moreover, the concept of good vs evil is also a common thread, with Bill Cipher usually being the main source of evil that the Naruto protagonists must face.
The theme of friendship, in a very twisted way, can also be found. In some fanfictions, the OC and Bill form an unlikely bond that challenges the traditional view of good and evil.
