Fanfiction about Harry becoming Naruto's sister: What are some interesting plot ideas?

One idea could be Naruto fully embracing the Kyuubi's power and using it in unique ways. For example, he might be able to transform into a new, more powerful form that combines his own skills with the raw power of the Kyuubi. He could also use the Kyuubi's chakra to perform new jutsus that are previously unthinkable. Another plot idea is that Naruto starts to think and act more like the Kyuubi in some aspects, which causes conflict among his friends and allies as they try to figure out if he's still the same Naruto they know.

A possible plot is that Naruto accidentally drinks a magic potion created by an eccentric inventor. This potion makes him handsome but also gives him some strange powers related to charm. He has to learn to control these new powers while dealing with the attention he gets from everyone, including some unwanted attention from villains who want to use his new charm for their own evil purposes. In the end, he figures out how to reverse the potion but decides to keep some of the confidence his new looks gave him.

One plot idea could be Naruto facing an extremely difficult mission during the Chunin Exams that tests not only his combat skills but also his strategic thinking. For example, he might have to rescue hostages in a complex maze-like fortress while being outnumbered by enemy ninja. Another idea is that Naruto discovers a new and unique jutsu during his training for the Chunin rank, which gives him an edge in the exams but also draws unwanted attention from other villages. Maybe he could form an unexpected alliance with a rival ninja during the exams to overcome a common enemy.

One idea could be that Naruto has to go through a series of ancient trials in a hidden and dangerous realm to become a sage. He might face illusions of his past failures and have to overcome them.

And a third could be that Naruto discovers a new form of chakra related to sage mode that he has to master while also fending off enemies who want to steal this power for themselves.

One idea could be that Naruto becomes undead and has to deal with the fact that he's no longer fully human. He might struggle with his new identity and how his friends will react. For example, Sasuke could be initially suspicious and conflicted about this new Naruto.

Well, a plot could involve Kisame's sister being a healer. Naruto gets seriously injured in a battle and she is the only one who can save him. As she heals him, they start to share their stories and dreams. This leads to her realizing that the Akatsuki's ways might not be right. Also, she could be in a love triangle between Naruto and a member of the Akatsuki, which would add a lot of drama to the story. There could also be a plot where she discovers a prophecy that Naruto is the key to saving the ninja world, and she decides to protect him at all costs.

Well, it could be that Fem Harry Potter has been hidden in the wizarding world all this time, not knowing about her true family in the Naruto universe.

Perhaps Harry's sister was kidnapped as a baby and raised by Death Eaters. She grows up believing in their cause until she discovers the truth about her family. This creates an internal struggle for her. She has to break free from the indoctrination and find a way to reconnect with Harry and the good side. Along the way, she might use the dark magic she was taught in a new and unexpected way to defeat Voldemort, like using a curse against him that he never expected because it was one of his own teachings.
