Sakura could be one of the characters. Since she has a long - standing relationship with Naruto in the original series, in a harem fanfiction, she might be part of it. Another one could be Hinata. She has always had deep feelings for Naruto, so it's likely for her to be included. And of course, Tenten herself is a central part of this harem concept in the fanfiction.
Ino might also be part of the harem. She's a strong and confident character who could add a different dynamic to the group. There could also be some minor female characters from other ninja villages. For instance, if Naruto has some diplomatic interactions with other villages, a female ninja from there might be attracted to him and end up being part of the harem. Tenten would then have to navigate relationships with these new additions.
Sakura is often a likely candidate. She has a long - standing relationship with Naruto in the original series, so it's easy to imagine her in a harem scenario with him.
For Naruto, Hinata is a strong possibility. She has always had deep feelings for Naruto. In the Street Fighter universe, Ibuki could be part of the harem. She is young and energetic. Also, Makoto would be a great character to include. She is known for her strong punches and kind heart. These characters would create a diverse harem around Naruto, with different fighting styles, personalities, and backstories contributing to the overall story of the fanfiction.
Well, there are several characters that could be in the harem. First, there's Temari. She has interacted with Naruto during the Chunin Exams and other events. Her strong personality and combat skills could make for an interesting dynamic in a harem story. Karin could also be a part of it. She has a connection to Sasuke, but in a different scenario, she could be attracted to Naruto. And then there's Anko Mitarashi. She's a bit of a wild card, but her unique personality and her role as a ninja could add a different flavor to the harem with Naruto at the center and Tenten also being part of it.
Definitely Pikachu. It's Ash's closest companion, so it could be part of the harem in a very unique way. Then there could be female Pokémon trainers like Misty and May. They have a history with Ash and could be part of this harem concept.
One possible antagonist could be a rogue ninja from another village. They might target Tenten for her unique weapon - handling skills, thinking they can use her to create powerful weapons for themselves. Naruto would then have to face this ninja to save Tenten.
In Fairy Tail, Mirajane would be a likely candidate. She's warm and friendly, and Naruto's positive attitude would likely draw her in. Wendy is also a possibility. She's young and impressionable, and Naruto's heroic nature could make her develop feelings for him. From Naruto's side, Hinata would be in the harem. Her shy yet determined nature would be an interesting contrast to the more outgoing Fairy Tail girls, and Naruto's presence in a new world might make her more bold in expressing her feelings for him.
Sakura could be one of the likely characters. She has a long - standing relationship with Naruto in the original series. In a fanfic with this concept, she might be drawn to Naruto's new connection with the fem Kyuubi out of curiosity or her own feelings for Naruto evolving. Hinata is also a strong candidate. Given her long - held feelings for Naruto, she would likely be part of the harem, especially as Naruto's power grows with the fem Kyuubi. And Ino could be there too. She's competitive and might see Naruto's new situation as something interesting and want to be part of it.
Hermione Granger is often a likely candidate. She has a deep connection with Harry throughout the original series, so it's easy to imagine her in a harem scenario. Ginny Weasley too, as she was Harry's love interest in the official books. And Luna Lovegood might also be included, given her unique personality and the fact that she and Harry are friends.
In addition to the obvious ones like James Potter, Sirius Black, Remus Lupin, and Severus Snape, some fanfictions might include other Hogwarts students. For instance, Lucius Malfoy could be an unexpected addition, as it would create a lot of interesting drama and conflict. There could also be some of the more minor characters like Frank Longbottom or Alice Fortescue, who could bring a different perspective to the harem. The beauty of fanfiction is that it can explore these less - likely pairings and relationships, making for a very diverse harem.
Luna Lovegood might be in the harem. Her unique perspective and kind - hearted nature could attract Harry. Also, Fleur Delacour could be included. She's a beautiful and powerful witch, and her allure and skills would make her a plausible addition to Harry's harem. And don't forget Cho Chang, who had a past with Harry. Her presence could add an element of unresolved feelings and history to the harem dynamic.
