His character development takes a negative turn. Instead of being the optimistic and determined Naruto we know, he becomes apathetic. His once - strong sense of justice fades away.
Well, at first, Naruto might have been on a positive character development path in the fanfiction. But as events unfold, like repeated disappointments or being used by others, he starts to withdraw. His development changes from a growth - oriented one to a regressive one where he stops believing in the values he used to uphold, such as friendship and loyalty.
He might become more withdrawn. Instead of being the energetic and enthusiastic Naruto we know, he could start to isolate himself from others.
Well, it makes the triangle less of a love triangle. With Naruto out of the picture in terms of caring for Sakura, it becomes more about Sakura and Sasuke's relationship without Naruto's interference. Sasuke may not have to deal with Naruto's rivalry in terms of Sakura's affection anymore.
Naruto's relationships with others will also be affected. His friends will be concerned and try to bring back the old Naruto. This struggle between his changed self and his friends' attempts to help can be a major part of his character development in the fanfiction. As he deals with his inner turmoil, he might learn more about himself and grow in ways that are different from his usual positive growth in the original story.
One possible reason could be that Naruto has faced so many betrayals and hardships in the fanfiction. For example, if his friends turned on him for some contrived reasons, it might lead him to stop caring. Another reason could be the constant failure in achieving his goals, like protecting the village but always being undermined by political intrigue within the fan - made story.
One possible reason could be that Naruto has finally realized that Sakura's heart has always been with Sasuke. After years of chasing after her and getting constantly rejected or overlooked, he just gets tired and decides to move on. He might start to focus more on his own personal growth and the other relationships in his life that are more reciprocal.
Naruto's caring changes their relationship in a positive way. At first, the Kyuubi saw Naruto as just a vessel. But as Naruto shows care, the Kyuubi starts to see him as an equal. For instance, it might start to communicate more openly with Naruto, sharing its knowledge of the ninja world.
One possible reason could be that Naruto has faced too many betrayals. Maybe his friends turned on him in the fanfic, which made him lose faith and stop caring.
In Naruto gender change lemon fanfiction, Naruto's character development is completely transformed. As a female, she might have to develop a different sense of self - confidence. Instead of the brash and bold Naruto we know as a male, she could become more nuanced in her self - expression. Her interactions with other characters, especially the male ones, will be different. For example, her rivalry with Sasuke could take on a more complex emotional layer, with possible undertones of unspoken attraction. This new dynamic would force Naruto to grow and adapt in ways she didn't have to before as a male, and her journey towards becoming a stronger ninja would be intertwined with her new gender - related experiences.
I'm not sure specifically as there could be many different takes on it. It might be a fanfiction where the character Izuku reaches a point of apathy or stops caring about things he previously held dear, like his dreams of becoming a hero or his relationships. It could be due to some traumatic event or a slow build - up of disappointments in the story's universe.
Naruto might become more conflicted. Since Madara had some extreme views, Naruto would have to grapple with those ideas. He could become more secretive as he tries to understand Madara's motives better without alarming his friends. For instance, he might start training alone more often to study Madara - inspired techniques.
