Well, if Naruto becomes the boogie man in the fanfiction, it could mean that he has some sort of dark or mysterious transformation. He might be feared by the villagers who once shunned him. This could lead to a whole new set of adventures where he has to either embrace this new identity or find a way to reverse it. Maybe he uses this new form to fight stronger enemies more effectively, taking advantage of the fear factor.
In this fanfiction, Naruto might use his new 'boogie man' status to play pranks on his friends in a more stealthy way. For example, he could use his newfound abilities to move around unseen and startle them at unexpected moments.
Perhaps in this fanfiction, Naruto becoming the boogie man gives him unique powers related to fear and illusion. He could enter people's nightmares and manipulate them, which could be used for good or bad. If used for good, he might help people face their fears. But if misused, it could lead to chaos. Also, his relationships with his comrades like Sasuke and Sakura would be greatly affected. Sasuke might be more intrigued or even more wary of Naruto, and Sakura might be scared at first but then try to understand and help Naruto control this new side of him.
