There could also be characters like Kakashi. His mysterious and experienced nature could be something that a Saiyan would be interested in. Hinata, with her gentle yet strong - hearted personality, could also be part of the harem. And Rock Lee, with his unwavering dedication to training and his unique fighting style, might also find a place among the group interacting with the Saiyan.
In terms of Saiyan characters, Goku could be an obvious choice if we are thinking of bringing in Saiyan elements from Dragon Ball. His pure - hearted and powerful nature would create a lot of interesting dynamics. Vegeta could also be there, with his pride and powerful combat skills. And then there could be some original Saiyan characters created just for this fanfiction, like a female Saiyan with a fiery personality who forms a special bond with the Naruto characters in the harem.
Well, Naruto himself could be a part of it. His determination and unique abilities might draw the attention of the Saiyan or vice versa. Sakura could also be in the harem, with her medical ninjutsu skills and strong - willed personality. And of course, Sasuke. His cool and powerful Uchiha abilities might make him an interesting addition to the group interacting with the Saiyan.
In the Naruto world, Sakura could be a potential character in the harem. She's strong - willed and has her own set of skills. From the Yugioh world, Anzu could be part of it. She's kind - hearted and often supports the main characters. Another from Naruto could be Hinata, who is shy but also very loyal. And from Yugioh, Mai Valentine, as she has a bold and confident personality.
There could be some original Arrancar characters created specifically for the fanfiction. For example, a young and curious Arrancar who is new to the ways of her kind. She meets Naruto and is immediately fascinated by his different appearance and abilities. And then there's a more experienced Arrancar who has seen many battles. She initially sees Naruto as a threat but then realizes his good intentions and slowly falls for him, becoming part of the harem.
For Naruto side, Sasuke could also be a character in this fanfiction. His cool and mysterious demeanor might draw the attention of Skyrim characters. In Skyrim, there's Serana. She is a vampire with a complex personality, and she could be interested in a Naruto character. Additionally, Ysolda, the young merchant in Whiterun, could be part of the harem as she is friendly and open - minded, and might be attracted to the unique qualities of Naruto characters.
Well, obviously Naruto himself would be the central male character. For the female characters in the harem, Sakura could be one. She might start to see Naruto in a new light when he overcomes his blindness with such tenacity. Hinata could also be part of it. Her shy and loving nature could be a great contrast to Naruto's more outgoing and determined personality in this scenario.
Temari could also be a potential character. Given her status in the Sand Village and her strong - willed nature, she would bring a different dynamic to the harem. There could also be some original characters created specifically for the fanfiction to add more variety.
Well, one could be a female ninja from the Uchiha clan. She might be strong - willed and have the Sharingan. Another could be a gentle - natured girl from the Hyuga clan, with the Byakugan. And of course, there could be a foreign ninja who has her own unique abilities and catches the heir's eye.
Naruto is a must. Kaguya, as a key part of the Naruto lore, would be in it. In terms of the harem, Ino could be one of the characters. She has always had an interest in Naruto to some extent. Tenten could also be part of it, perhaps drawn to Naruto's new Saiyan - like strength. And from the Saiyan side, Raditz could be introduced, creating some conflict as he initially tries to take advantage of Naruto's Saiyan powers but later might become an ally. There could also be some original characters created just for this fanfic.
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.
In a Naruto and Percy Jackson mass harem fanfiction, Naruto's side might include Tenten and Temari. They are strong and independent characters who could add interesting dynamics to the harem. For Percy Jackson, Reyna could be in the harem. She has leadership qualities and her Roman heritage could bring in new elements. And let's not forget some minor characters from both universes could be given more spotlight in the harem, like some of the nymphs from Percy Jackson's world or some of the kunoichi trainees in Naruto's world.
Tsunade could be part of it. Since she is a Senju, she could be a powerful ally and also someone who helps Naruto and Hinata navigate the complex relationships in the harem. Also, Nawaki Senju could be brought back in some way, maybe as a spirit or through some time - travel plot device. He could befriend Naruto and be involved in the growth of the relationships within the harem.
