One way to develop Naruto's character is by exploring his leadership skills in the context of being an emperor avatar. He could start off as a hesitant leader, still used to being the underdog in the ninja world. But as he faces challenges, like economic problems in his new realm or threats from neighboring kingdoms, he grows into a confident and wise leader. His experiences with his friends in the Leaf Village, such as Sasuke and Sakura, could also influence how he forms his council and makes decisions in his new role.
