Lucy could be a likely member. She has a close relationship with Natsu already in the original story. Another one could be Erza. Her strong and independent nature might be attracted to Natsu's new godlike power. And Wendy, being young and impressionable, might also be part of the harem as she looks up to Natsu.
Definitely, Lucy is a top candidate. She and Natsu have been through a lot together. Erza, with her unwavering strength and leadership qualities, could be in the harem as she might be intrigued by Natsu's transformation. Juvia could also be part of it. Given her obsessive love for Gray, she might transfer some of that intensity to Natsu in this 'godlike' scenario. Plus, Levy, who is intelligent and kind, could be attracted to Natsu's new power and his heroic nature.
Well, obviously Lucy from Fairy Tail would be a likely candidate. She already has a strong connection with Natsu in the original series. Then from the world of Bleach, Rukia could be an interesting addition. Her cool and collected nature would contrast with Natsu's hot - headedness, and her Soul Reaper powers would add an interesting dynamic to the harem. Also, from Attack on Titan, Mikasa could be in the harem. Her strong combat skills and protective nature towards Eren could translate into a similar protectiveness towards Natsu in the fanfiction.
In addition to Lucy and Erza, there could be other female characters from the series. Maybe some minor characters who have always admired Natsu from afar. For example, that one girl from the guild who always blushes when Natsu is around. Another possibility is a powerful female dragon who sees Natsu's transformation into a Dragon God as a sign of his worthiness. She might join his harem, bringing a different kind of relationship dynamic as she has her own dragon - like qualities and power. And there could be a female mage from a different guild who hears about Natsu's new status and is intrigued, eventually becoming part of his harem.
Well, Mirajane could be part of the harem. She has a motherly side and would want to comfort Natsu if he was betrayed. Levy is also smart and resourceful, and she could use her skills to help Natsu out. Juvia, with her obsessive love for Gray, might transfer some of that intense loyalty to Natsu if she saw him in a desperate situation after being betrayed.
Well, consider the idea of some new characters being introduced as part of the harem too. Maybe a Gem from a far - off colony who has heard of Steven's exploits and travels to meet him. Or a human girl who lives near the beach where Steven often is and becomes smitten with him. The harem could also include a fusion of two Gems that has a unique personality of its own and is attracted to Steven's inclusive and accepting nature. There are so many possibilities when thinking about who could be part of the harem in this fanfiction.
One possible plotline could be Natsu's godlike powers attracting various characters to form a harem. Maybe his newfound powers make him a target as well as an object of admiration, leading to different relationships within the harem.
Well, obviously Fuu would be one of the main members. Sakura could also be part of it as she has always had a connection with Naruto. Ino might be another possibility as she is strong - willed and could be attracted to Naruto's growth. And perhaps some new characters from Fuu's world or other parts of Naruto's travels could also join.
Aside from Kushina, Sakura could be a potential member. She might be attracted to Dark Naruto's new - found power and his different personality. Hinata could also be in the harem. Her gentle nature might be drawn to the complex and powerful Dark Naruto. Another could be Temari. Given her own strong - willed nature, she could be interested in Dark Naruto's power and his relationship with Kushina.
Definitely Sasuke. He has a complex relationship with Naruto, and in a gender - bender situation, that relationship could take on a whole new romantic dimension. Sakura could also be in the harem. She has always had strong feelings for Sasuke, but with Naruto's new form, she might develop different feelings. And then there's Hinata, who has always been in love with Naruto, and this gender - bender concept could add more depth to her feelings.
Liu Kang is also a possibility. In some fanfiction scenarios, the gender roles can be a bit more fluid. His noble and powerful presence could be part of the harem. Then there's Scorpion. His loyalty and intensity could make him an interesting addition to the harem around the OC. There could be a lot of drama with his vendetta-filled past.
In a 'Food Wars Soma x Harem Fanfiction', Erina Nakiri would be a top candidate for the harem. She has a long - standing rivalry and growing affection for Soma. Megumi Tadokoro is another, with her gentle nature and admiration for Soma. Alice Nakiri could also be included. She is Erina's cousin and has interacted with Soma in a competitive yet friendly way. And let's not forget Ryoko Sakaki, who is part of the Polar Star Dormitory and could easily be part of the harem due to her proximity to Soma.
