Perhaps the grandson is on a mission to redeem his family name. He discovers a hidden power that Madara had but never fully utilized.

Along the journey, he forms a team of unlikely allies who help him in his quest, and they all grow together as they face various challenges.
One possible plot could be that Naruto discovers his true heritage as the grandson of Madara and Hashirama. This revelation could lead to a power struggle within the village as some might fear his new - found connection to such powerful predecessors.

In a fanfiction, Madara Uchiha's grandson could have unique powers. Since the Uchiha are known for their Sharingan, perhaps he has an evolved form of it.

In fanfiction, the author could create a scenario where there was a secret relationship between an Uzumaki ancestor of Naruto and an Uchiha. This relationship could have been hidden for generations.

He could also explore the history of the Uchiha more deeply and uncover secrets that were lost in the original story.
