The plot could be about Naruto suddenly discovering he has Diclonius powers. He might have to hide it at first because people in the Hidden Leaf Village would be afraid of his new abilities. Then, he could start training to control his Diclonius powers, like his vectors, while still dealing with the regular threats in the Naruto world, like Akatsuki.
In a 'Naruto is a Diclonius fanfiction' plot, it could be that an ancient jutsu gone wrong causes Naruto to become a Diclonius. This new form gives him unique powers but also attracts unwanted attention from outside forces. The Hidden Leaf Village might be divided on whether to trust Naruto or not. Naruto would have to struggle to gain their trust back while also exploring the origins of his new Diclonius nature. He could meet other characters who either help him understand his new self or try to use him for their own evil purposes.
One idea could be a male diclonius who finds himself in a world where he has to protect a group of female characters from various threats. Another could be a story where he is on a journey to discover his true powers and along the way, he gathers a harem of different female diclonius with unique abilities.
A plot could involve a male Diclonius who discovers he has a unique power among his kind. He is then hunted by other Diclonius who see him as a threat or a valuable asset. As he tries to evade them, he stumbles upon a hidden community of Diclonius who have different ideals and he has to decide whether to join them or continue on his own path. He could also be on a quest to find out the origin of his kind and the true purpose of their powers.
Yes, there might be such fanfiction. However, I haven't read it specifically. Diclonius is from a different anime concept, and when combined with Naruto in fanfiction, it could potentially create some really interesting crossovers. It might involve Naruto characters having some of the characteristics or facing situations related to Diclonius, like the horns and special powers.
To create a compelling male Diclonius character, give him complex emotions. He could be conflicted about his powers, feeling both pride in his strength and guilt for the harm they can cause. Also, give him a backstory. Maybe he was an outcast among humans before he knew he was a Diclonius. Physical traits can also be important. Describe his horns or his unique Diclonius features in an interesting way.
He could be characterized as strong and protective. Since he is a diclonius, he would have certain powers that he can use to safeguard the females in his harem.
Perhaps there's a prophecy that Naruto and Chichi together can stop an impending doom. But they come from different worlds and cultures. Naruto has to convince Chichi to believe in the prophecy and join him. Along their journey, they learn about each other's worlds, like Naruto shows Chichi his ninja village and its unique customs, and Chichi teaches Naruto about her family traditions. Their relationship grows as they work towards fulfilling the prophecy.
Well, one possibility could be that Naruto has some unique abilities inherited from Hermes. Maybe he has super speed like Hermes, which would completely change the way battles play out in the Naruto universe. He could use this speed to outmaneuver his opponents in a fight, and it would be a new and exciting addition to his existing skills.
If Naruto was adopted by Kyuubi in fanfiction, it could lead to a completely different Naruto. He might be more confident earlier on. Since Kyuubi is a very powerful being, Naruto could be trained in unique ways. For example, he could learn how to harness Kyuubi's power more effectively without the need for the traditional methods of suppressing and drawing on the fox's chakra. This would change his relationships with his peers too. He might be seen as an oddity, but also as someone with great potential.
Well, it could be that Konan finds Naruto alone and decides to take him in. Maybe she sees his potential and wants to protect him from the harsh world of shinobi. She could teach him some of her own unique skills, like her paper ninjutsu. And Naruto, with his positive attitude, might influence Konan in return, making her more open and hopeful.
Well, if Naruto was raised by Whis, he'd likely be exposed to a whole new world of power levels. Whis could introduce Naruto to the concept of godly ki. Naruto's ninjutsu might be enhanced or even combined with ki - based attacks. Also, Whis's sense of discipline would surely have an impact on Naruto's growth, both as a fighter and as a person. Maybe Naruto would become more refined in his fighting style, rather than relying solely on brute force like he sometimes does in the original story.
