Well, a major theme is the struggle for acceptance. In these fanfictions, the immortal shapeshifter is often different from the normal inhabitants of the Naruto world.

Shapeshifter fiction is a genre where the main concept involves characters that can change their physical form.

Perhaps a group of rogue ninjas who are threatened by Naruto's shapeshifting ability. They might see him as a threat to their plans and try to eliminate him. They could be led by a mastermind who is well - versed in countering shapeshifting techniques.
