A possible plot idea for a Naruto Lightning Sage Fanfiction is that the protagonist, as a lightning sage, travels to different dimensions to gather fragments of a powerful lightning - based artifact. In each dimension, they face unique challenges and enemies. They might also encounter alternate versions of known Naruto characters. Along the way, they learn more about the true nature of the lightning sage power and how it can be used not just for combat, but also for restoration and peace - building in the Naruto universe.
Perhaps a story where Naruto loses his Sage Chakra abilities due to some dark magic or a curse. He then has to go on a journey to regain it.
