In the 'naruto becomes twisted fanfic', Naruto might develop a twisted sense of justice. He could start to think that the ends justify the means, no matter how cruel those means are. For instance, he might use innocent people as bait to catch his enemies. His relationship with his sensei could also be affected. His sensei might try to bring him back to the right path, but Naruto, in his twisted state, could see this as interference and turn against his teacher.
Perhaps Naruto could be influenced by a dark power. In the 'naruto becomes twisted fanfic', this power might make him see his enemies not as people to be redeemed but as pests to be exterminated. His normally positive attitude towards training could turn into an obsessive pursuit of power at any cost. He may even turn against his village if he thinks they are holding him back from his new goals. This would create a lot of conflict and drama within the story.
One possible plot development could be Naruto's ideals getting warped due to some traumatic event. For example, if he fails to save a dear friend, he might start to believe that the only way to achieve true peace is through extreme force. Another development could be his relationships turning sour. Maybe his friends start to fear his new, twisted self and Naruto, feeling betrayed, becomes even more deviated from his original self. Also, his view of the ninja world could change completely, seeing it as a place that needs to be remade in his own image rather than following the traditional ways.
Well, one possible plot development could be Naruto facing different challenges as a female in the ninja world. For example, she might have to deal with gender discrimination within the ninja clans. Another could be her relationships with other characters changing. Maybe Sasuke would see her in a new light and their dynamic would be different. Also, Naruto as a female could inspire other female characters to be more confident and break gender barriers in the shinobi society.
One possible plot development could be Naruto struggling to control his new dragon powers. He might accidentally cause destruction in the Hidden Leaf Village at first. Then, he'd have to go on a journey to learn how to master these powers, perhaps with the help of an old sage or a mysterious dragon - like creature.
In this fanfiction, perhaps Naruto's physical abilities are enhanced as the Kyuubi's kit. He might be able to move faster, jump higher, and his strength could be superhuman. Also, his relationship with Sasuke could change. Sasuke might see Naruto as an even greater threat or, on the other hand, an ally he needs to understand better. And Naruto could start to have a different understanding of his own identity and place in the ninja world.
One possible plot development could be Harry having to deal with the new political and social responsibilities that come with being a lord. He might have to make decisions regarding the welfare of his land and the people in it.
A third possible plot development could be the exploration of family values. Naruto, having grown up longing for a family, would be very committed to building a good family environment for Mordred. This could involve teaching Mordred about love, trust, and the importance of family bonds. Mordred, who may not have had such a positive family experience before, would then have to learn and grow in this new family setting. There could also be moments where Mordred has to defend Naruto or their family from external threats, which would strengthen their bond further.
One possible plot development could be Naruto leaving due to a misunderstanding. For example, if he is wrongly accused of a crime within the team. Another could be that he feels he is holding the team back in some way and decides to leave on his own to become stronger alone. Maybe he has a personal goal that he believes he can't achieve while still being part of Team 7.
One possible plot development could be that Naruto uses Kirin to surprise his enemies. Since it's not a jutsu associated with him usually, it would catch his foes off - guard.
One possible plot development could be the initial shock and adjustment for both Naruto and Mei. They would have to deal with the reactions of their respective villages. Naruto's friends in Konoha might be surprised, and Mei's allies in Kirigakure would also have their thoughts.
One possible plot development is that Nagato and Naruto form an alliance to take on a new, greater threat. This threat could be an ancient evil that requires both Nagato's power and Naruto's spirit. Another development could be Nagato using his abilities to help Naruto unlock new powers or forms. For example, he might help Naruto better understand the Sage of Six Paths' power within him.
Naruto might become more confident. Being a dragon gives him new powers, and with that comes a sense of self - assurance. He may also become more solitary at first as he tries to understand his new form. But as he gets used to it, he'll start to integrate his dragon side with his ninja self.
