Well, from Naruto, Shikamaru could be there. He's intelligent and could offer some interesting strategies. And Ino with her mind - related abilities. In the Marvel world, Black Panther's sister Shuri could be a great character to include. She's smart and resourceful. Also, Ant - Man's daughter Cassie Lang could be part of the group. They could all come together in a story full of adventure and friendship, without any inappropriate or adult - themed content.
In a family - friendly version, Naruto would be there of course. Hinata could also be part of it. Her shy yet determined nature would be interesting. In the Marvel universe, we could have Storm. She has control over the weather and is a very noble character. And then there's Gamora. She's a strong and complex character who could have some great interactions with the Naruto characters without any inappropriate elements.
Some other potential characters could be Anko Mitarashi. She has a unique personality and could add an interesting flavor to the harem. Kurenai Yuhi could also be a possibility, with her experience and maturity. And from the new generation, Sarada could potentially be in a future - set version of this fanfiction, with new twists on the arranged marriage concept.
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.
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.
Sif from Asgard is a great candidate. Her loyalty and warrior spirit would contrast well with the OC. And then there's Kitty Pryde. Her intelligence and phasing ability could lead to some really cool scenarios where she helps the OC out of tricky situations, and of course, romantic relationships could develop from there.
In 'Luffy Lemon Harem Fanfiction', Nami is an obvious choice. She's always there to scold and care for Luffy at the same time. Robin, with her intelligence and elegance, could easily be part of it. There could be a girl from a sky island. Since Luffy has this amazing ability to make friends and influence people, this sky island girl might be fascinated by his adventures and fall for him. Additionally, a female marine who has a change of heart after seeing Luffy's selfless acts could also be in the harem.
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.
Well, the plot could be about Naruto creating a clone Naruko for a mission. They could team up to solve puzzles or overcome obstacles in a mysterious dungeon. The focus could be on their combined skills, like Naruto's Rasengan and Naruko's agility, and how they learn to trust and rely on each other during the adventure.
Spiderman is the key, of course. In addition to the well - known female characters from the Spider - Man universe, there might be other characters from the Marvel world who cross paths with him and end up in the harem. For instance, Black Cat could be a likely candidate. She has that alluring and mysterious personality that would fit well in this kind of scenario. Also, characters from different dimensions or alternate universes could be brought in, adding an element of the unexpected to the harem and the overall story.
