Well, in a lot of these fanfics, characters like Levy from Fairy Tail show up in Naruto's harem. Her intelligence and her friendship - based personality can be an interesting addition. Then there's Yoruichi from Bleach. Her cat - like form and her powerful combat skills make her a unique member of the harem. Also, Rias from High School DxD is a common addition. Her devilish charm and her leadership abilities create a complex relationship with Naruto in the fanfic scenarios.
One of the popular characters is Hinata from Naruto itself. Since she already has feelings for Naruto in the original series, she is often part of the harem in crossover fanfics too. From other series, Lucy from Fairy Tail is also common. Her magical abilities and her kind - hearted nature can blend well with Naruto's character. Additionally, Saber from Fate/stay night is often included. Her noble and powerful presence can add a different flavor to Naruto's harem.
Naruto and Ichigo are very common main characters. Naruto's energetic and friendly personality makes him a likely candidate to attract a harem in a crossover. Ichigo, with his cool and strong - willed nature, is also a popular choice. Among the female characters, Sakura from Naruto and Orihime from Bleach are often included. Sakura's growth as a kunoichi and her feelings for Naruto can add drama to the harem dynamic. Orihime's kind heart and unique powers can make her an interesting part of the harem in a crossover story.
In a 'naruto is in a au harem fanfic', aside from the obvious choices like Sakura and Hinata, characters like Temari could be in Naruto's harem. She's from another village and has a strong personality. Her presence would bring in an element of cross - village relations. Karui is also a possibility. She's feisty and has her own set of skills. And then there's Kurenai, the jonin. She could be an interesting addition to the harem, with her experience and calm demeanor.
In Naruto's harem, Hinata is a very possible character. She has always had deep feelings for Naruto and would surely follow him into this crossover adventure. From Yu - Gi - Oh, Anzu Mazaki could be there. She is kind and has a caring nature, and Naruto's heroism might make her develop feelings for him. Additionally, Serenity Wheeler could also be part of the harem. She is gentle and Naruto's selfless actions could win her over, especially in the face of the challenges that come with the crossover of the two very different universes.
Hinata is also often included. Given her long - standing crush on Naruto in the official story, it's easy for fanfic writers to develop their relationship into a full - fledged romantic one in a harem scenario.
Sakura could be a popular choice. She has a long - standing relationship with Naruto in the original series, so it's easy to imagine her in a harem setting. Hinata is also very likely to be in the harem as she has deep feelings for Naruto. And then there's Ino, who has her own charm and could add an interesting dynamic to the harem.
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.
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.
From the Naruto universe, Sakura would be a likely candidate. She's strong - willed and has a history of being attracted to powerful guys like Sasuke, so Naruto's new - found crossovery powers could draw her in. In the Percy Jackson world, Annabeth is smart and independent. She might be intrigued by Naruto's different fighting style and unique upbringing as a ninja. Also, Piper has the ability to charm - speak, but she could also be charmed by Naruto's genuine nature.
From Naruto, Tenten could be in the harem. She is a skilled weapon user. In the DBZ universe, Marron could be part of it. She is Krillin's daughter and could have her own story arc in this harem situation.

Besides the main female characters from the original series, some fanfictions also include Tenten. She brings her weapon - master skills and a no - nonsense attitude to the harem. Another character that might show up is Temari. Her strong - willed and independent nature from the Sand Village can create interesting interactions within the harem.
