The fem Naruto stands out as a very interesting character. Her character development can be really unique. For example, she might face different challenges in terms of romance and acceptance in the ninja community. Another interesting female character could be Anko. In these fanfics, she could be a sort of anti - hero figure who helps the fem Naruto in unexpected ways. She has her own dark past and secrets, and when she teams up with the fem Naruto, it can create some really exciting story arcs. And Tenten could also be a great character. She might get more spotlight in fem Naruto reincarnation fanfiction, showing off her skills and having more interactions with other female characters in a more prominent way.
Gaara could be an interesting addition too. Since he has his own complex backstory with power and isolation, he might see fem Naruto as a kindred spirit in a way. He could approach her to learn more about how she's handling the power and status, and perhaps they could form an alliance based on their unique positions in the world.
The main character who is reincarnated is often very interesting. They bring a fresh perspective to the Naruto world. Also, any characters that interact with the reincarnated one in a unique way, like an old - school ninja who is skeptical of this new 'reincarnated' concept.
Sasuke is often a common supporting character. He might have his own reasons for following or helping fem Naruto in exile. Maybe he feels a sense of loyalty or he too has issues with the village. Another could be Kakashi. He may secretly support fem Naruto and provide her with some guidance from afar.
Sakura is often a common supporting character. She can be a great friend or even a rival to fem Naruto in these fanfictions. Sasuke is also very common, as his relationship with Naruto in the original series can be re - imagined in interesting ways with a female Naruto. Kakashi could also play a crucial role, perhaps as a mentor to fem Naruto on her journey to become Hokage.
Naruto himself is obviously a key character in this type of fanfiction. Then there's Sasuke. Given his popularity and complex personality, he can add a lot of drama to the harem situation. Shikamaru is also likely to be part of it. His laid - back but intelligent nature can create interesting interactions with Fem Haku. Another one could be Gaara. His past and his new - found path of friendship could lead to him having feelings for Fem Haku in the fanfiction.
Definitely Harry Potter and Naruto themselves are very popular. People like to imagine Harry in the Naruto world using his magic skills and adapting to ninjutsu. And Naruto in Hogwarts, using his ninja abilities and his never - give - up attitude in the wizarding world. Hermione is also a popular choice. Her intelligence would be very interesting to see in the Naruto world, perhaps she could use her smarts to study chakra in a new way.
Sasuke is often a popular supporting character. His relationship with fem Naruto can be complex, especially with the added element of her being half - demon. He might be both intrigued and wary. Sakura could also be popular. She could serve as a contrast to fem Naruto, perhaps initially being more fearful or judgmental of her half - demon nature but then growing to accept her. Kakashi is another one. His wisdom and experience can be crucial in guiding fem Naruto through the difficulties of being half - demon in the village.

Sasuke could also be a really engaging character. Maybe in the fanfiction, he has a different path or a new motivation that makes his story more captivating.

And his interactions with other characters would be different too, adding more depth to his character.
Definitely Naruto's son, Boruto. He has his own set of challenges and goals that make him really interesting. He wants to be his own person rather than just living in Naruto's shadow. Then there's Sarada, Sasuke's daughter. She's strong - willed and determined to prove herself as a great ninja. And Mitsuki, he's an enigma with his unique abilities and mysterious origin.
