In many sakura haruno reverse harem fanfictions, Naruto and Sasuke are almost always there. Naruto's energetic and kind - hearted nature contrasts well with Sasuke's more brooding personality, creating an interesting dynamic around Sakura. Kakashi can also be part of it in some stories, with his mysterious and experienced character adding another layer to the relationships. And then there are often new male characters introduced, like a foreign shinobi who is attracted to Sakura's strength and beauty.
Well, Naruto and Sasuke are the most common ones, no doubt. But other characters like Kiba can also show up. Kiba with his bold and somewhat wild nature can make for an interesting addition to the reverse harem. Neji is another character that might be included in some fanfictions. His calm and composed self can create a different kind of relationship with Sakura compared to the others. And of course, as I said before, original characters are often created to make the reverse harem more diverse and exciting.
One popular sakura haruno reverse harem fanfiction is 'Sakura's Many Loves'. In this story, Sakura is surrounded by a group of guys who all have different personalities and feelings for her. Another one could be 'Sakura in the Reverse Harem World' where she has to navigate through the complex relationships with the male characters. There are also some on fanfiction websites like Archive of Our Own that might be worth exploring.
Naruto can also be paired with Sakura in these fanfictions. Since they are such close friends in the original, in a reincarnation scenario, their friendship could potentially turn into something more romantic. They could support each other in different ways than in their past lives.
In certain 'sakura haruno revenge fanfiction', Orochimaru might be the antagonist. Given his history of using people for his experiments and causing harm, Sakura could decide to take revenge on him, perhaps to stop his evil plans and avenge those who have been affected by his actions.
Another theme is self - discovery. The male character may play a role in helping Sakura to learn more about herself, her strengths, and her weaknesses. In some fanfictions, Sakura also helps the male character in his own self - discovery journey.
Often, Kakashi is paired with Sakura in these fanfictions. Since he is her teacher, in a badass multi fanfiction, he might take her on special missions where she really shows her skills. Also, Rock Lee could be paired with her. They both have a strong will and in fanfiction, they could team up to take on some really tough opponents. Their relationship can be developed in a more action - packed and interesting way.
There could be the patients, of course. Each patient might have their own unique backstory and personality. Maybe there's a young patient who is dealing with trauma, and Sakura has to find a way to reach out to them.
I don't know for sure, but since it's a fanfiction centered around Sakura Haruno, she is the main focus. However, it may also feature characters who had a major impact on her life. This could include her sensei, like Tsunade, who trained her in medical ninjutsu. There's also a possibility that new characters created specifically for this fanfiction could be main characters as well, but that's just speculation.
In some Sakura Haruno alpha fanfiction, Kakashi could be a significant character. He might act as a mentor to Sakura in her new alpha role. He could guide her in making difficult decisions, like when she has to choose between the safety of the village and the life of a comrade.
Harry Potter himself is very common. His heroic nature and status as the Boy Who Lived make him an appealing character in a reverse harem. Draco Malfoy is also often included. His complex personality, from being a bully to having deeper layers, adds an interesting dynamic. Ron Weasley is another one. His loyalty and his relationship with Harry can be explored in different ways in the context of a reverse harem.
Another theme could be his relationships. He might have different kinds of friendships or romances compared to the female Sakura. For instance, his relationship with Naruto could take on a different dynamic, like a more brotherly or rival - like bond. Also, his relationship with Sasuke could be explored in new ways, perhaps as comrades with a different level of mutual respect.
