Well, Naruto is the central male figure. He has his orange jumpsuit and his dream of becoming Hokage. Fu, on the other hand, is a key female character. She has her own set of skills and a personality that makes her stand out. In a harem fanfiction, Naruto is surrounded by characters like Fu, and there could be other female characters from the Naruto universe that might be added to the mix, like maybe some of the kunoichi from Konoha or other villages who get involved with Naruto's story in this particular fanfiction.
One possible plot idea could be Naruto going on a mission with Fu and gradually developing a deep friendship that could potentially turn into a romantic relationship. Another could be a story where Fu's unique abilities play a crucial role in helping Naruto face a powerful enemy in the Naruto universe.
Definitely Hinata. Her love for Naruto is well - known. Sakura, too, as she has grown closer to Naruto over the years. Ino might also be in the harem. She has had her own moments with Naruto and her skills as a ninja could be an asset. And perhaps Karui from the Cloud Village. After Naruto's peace - making efforts between the villages, she could have developed feelings for him.
Sakura would be a likely candidate. She has a long - standing relationship with Naruto, so she could be part of the harem. Hinata is also a strong possibility as she has deep feelings for Naruto. And Ino, who has known Naruto for a long time and has her own charm, could also be in the harem.
Sakura could be in Naruto's harem. In the original series, she had a long - standing relationship with Naruto. In this fanfiction, with Naruto being 'dark godlike', she might be drawn to his new power and the mystery surrounding him. Also, Hinata would be a likely candidate. Her long - held feelings for Naruto could intensify with his new status, and she would be part of his harem due to her loyalty and love for him.
Sakura could be in the harem. She has a long - standing relationship with Naruto in the original series, and in this fanfiction, his Saiyan powers might make her see him in a new light. Hinata is also a likely candidate. Her admiration for Naruto could turn into a deeper relationship given his Saiyan - like abilities.
Perhaps a young and rebellious kung fu prodigy. This character might be initially reluctant to teach Naruto but is eventually won over by Naruto's tenacity. They would have a more dynamic relationship, with the young master constantly challenging Naruto to think outside the box and Naruto in turn teaching the master about the ninja way.
Hinata could be a likely member. She has always had feelings for Naruto. Sakura might also be part of it, as she is an important female character in the Naruto series. And perhaps Tenten, who is strong and independent and could be attracted to Naruto's new winged form.
In such a fanfiction, Princess Bubblegum from Adventure Time could be in the harem. She's intelligent and powerful, and Naruto's unique skills and personality might attract her. Also, Sakura from Naruto could be part of it. Since she has a history with Naruto and in this crossover, she could be part of the group vying for his attention. And Marceline too. Her cool and edgy nature might be drawn to Naruto's heroic side.
It's not appropriate. The 'Naruto' series has a positive and inspiring theme. Fanfiction with such inappropriate concepts as nudist and harem not only disrespects the original work but also can have a negative impact on the audience, especially younger fans.
