In a 'Naruto is a prince' fanfiction, perhaps Naruto's princely heritage is tied to some ancient prophecy. As a prince, he may have to unite different ninja clans or villages under his rule to fulfill the prophecy. Or maybe he has to deal with political intrigue within his own royal family, all while still being the goofy and determined Naruto we know, trying to bring peace to the ninja world.
One possible plotline could be that Naruto discovers he is a prince from a hidden or lost kingdom. This could lead to him having to learn royal etiquette while still trying to maintain his ninja ways. Another plotline might be that his status as a prince makes him a target, and he has to protect his new - found royalty while also protecting the Hidden Leaf Village.
One possible plotline could be a situation where Naruto is split into two versions of himself, maybe by some sort of jutsu gone wrong. And as they get to know each other better, they end up kissing as a way to reunite or merge back into one. Another could be in a dream sequence where Naruto is exploring his self - worth and in this dream, he kisses his own reflection which then turns into another version of himself.
Well, a possible plotline might involve Naruto being possessed by the essence of the Shredder. As a result, he starts to act more like the Shredder in his own world. He could form his own group of followers similar to the Foot Clan and try to take over the ninja villages. His friends would then have to find a way to break the possession and bring back the old Naruto. Or, perhaps Naruto willingly takes on the Shredder role to gain new powers to fight a greater evil in his world, but he has to struggle with the darker aspects of the Shredder's personality.
One possible plotline could be Naruto having to adapt to his new - found disability. He might struggle with his self - worth as a ninja, since being crippled could limit his physical abilities. He could then focus on developing other skills, like his strategic thinking or his ability to train others.
One possible plotline could be Ash discovering his heritage as the prince of aura and having to learn how to control and use his new - found powers. For example, he might struggle at first but then gradually master them to face stronger opponents.
One possible plotline could be the exploration of the Torn Prince's backstory.

One possible plotline could be that Harry discovers some dark family secrets that lead him to embrace the dark side. Maybe he finds out that his connection to Voldemort is more complex than he thought and decides to use that power for his own gain instead of fighting against it.
One possible plotline could be that Naruto is constantly rejected by the village he is trying to protect. This betrayal and lack of acceptance could gradually turn him dark. For example, if the villagers start to blame him for every bad thing that happens, even when it's not his fault. Another plotline might involve Naruto losing someone very close to him, like Sasuke, in a way that he blames the shinobi world for. This could lead to him deciding to take revenge on the world and turn to darker methods of achieving his goals. Maybe he starts to use forbidden jutsu without hesitation, seeing it as a means to an end.
A possible plotline could be that Calypso, with her alluring powers, tries to tempt Naruto away from his path of becoming Hokage.
