Well, Naruto is the main character. Then you'll often see the female characters from his age group like Karin. Karin has her own unique abilities and a somewhat obsessive personality when it comes to Sasuke, but in these fanfictions, she could be part of Naruto's harem. Temari could also be there. With her no - nonsense attitude from Suna, she would create a contrast to some of the more gentle - natured characters in the harem.
Sakura is often one of the common female characters. In the original Naruto series, she has a pre - existing relationship with Naruto, so it's easy to include her in a harem scenario.
Well, Naruto is a must - have. The female ninja like Sakura, who is strong - willed and has a long - standing relationship with Naruto. Hinata, with her shy yet determined personality, is also very common. Ino, who has her own charm and skills. Tenten could also be a character in these fanfictions. She is often overlooked in the original series but can have a more prominent role in a harem fanfiction. And Kurenai, with her experience and mystery, can also be part of the story.
Hinata is often a part of the harem. In the original series, she has strong feelings for Naruto. Sakura can also be included. Even though she had feelings for Sasuke initially, in fanfiction, she can end up in Naruto's harem. Tenten is another character that might be written into the harem, as she is a strong and independent kunoichi.
Obviously, Naruto and Naruko are the main characters. Naruto, with his determination and unique abilities. And Naruko, who likely has her own charm and skills in this fanfiction.
Well, often there are plots where Naruto's futa nature brings about a change in the traditional power structure in the story. Maybe the harem members are initially skeptical or even afraid, but as they get to know Naruto better, they come to accept and even love this new side of him. It could also involve Naruto using his abilities to help the harem members achieve their own goals, like Sakura becoming a better medical ninja with Naruto's support.
Obviously Naruto and Sonic are common characters as it's in the title. There could also be female characters like Sakura from Naruto series and Amy Rose from Sonic series.
For Ichigo's harem, Orihime and Rukia are very common. Orihime with her kind heart and strong powers of healing, and Rukia being the one who introduced Ichigo to the world of Soul Reapers. In Naruto's case, Hinata and Sakura are often part of his harem. Hinata because of her long - standing love for Naruto, and Sakura being one of Naruto's closest friends.
Ino is another character that often shows up. Her confident and sometimes competitive personality can add spice to the harem. There are also some fan - made or less - prominent female characters from the Naruto world that get included. For example, some fanfictions might include female ninjas from other villages who become part of Naruto's harem after interacting with him during diplomatic or combat situations.
Naruto himself is always interesting. His unique personality and his journey from an outcast to a hero provide a lot of material for the fanfiction. His ability to form deep connections with the harem members despite his busy ninja life is a key aspect. Kin is also quite fascinating. Her own backstory and her relationship with Naruto can be explored in many different ways in the fanfiction, especially how she fits into the harem dynamic.
Well, Naruto is obviously one of the main characters. He brings his own set of skills, personality, and his journey from the original Naruto series into this fanfiction. Tsume is another key character, with her unique wolf - like traits and her own backstory that can be explored in relation to Naruto and the harem concept.
