If Natsu is a girl in this fanfiction, her character might change in terms of her relationships. For instance, she may be more self - conscious about her appearance compared to when she was male. Also, her interactions with male characters like Gray could shift. Instead of their typical rival - like banter, there could be a more complex emotional undertone, like a friendly - rivalry with a hint of romantic tension perhaps.
To develop Natsu further, we could explore his godly side more. Maybe he starts to have visions or dreams related to his godly powers. This could make him more introspective and less impulsive at times. He could also start to learn new forms of magic that are related to his godly heritage.
Natsu is often seen as a strong and passionate character. His determination in battles and his loyalty to his friends make him an interesting subject for fanfiction. Writers can explore different scenarios where he shows his strength or his softer side.
In many fanfictions, Natsu's character develops by becoming more responsible. As the Red Dragon Emperor, he has greater power and with it comes more responsibility. He starts to think more about the consequences of his actions and how they affect not only his friends but also the world around him.
In a fanfic where Natsu is raised by a light - dragon, his character would develop in a very different way. The light - dragon's influence would likely make him more of a beacon of hope. He would be more focused on justice and helping others in a more positive, guiding light - kind of way. His powers would be different, and he would have to learn to control light - based abilities. This would require a different kind of self - discipline compared to controlling fire. His relationships would also be affected. For instance, he might be more of a role model to the younger members of the guild, and his interactions with his enemies would be more about converting them to the side of good rather than just defeating them.
Natsu's character development in this fanfiction might involve him becoming more responsible. With his end form, he has greater power and with that comes the need to use it wisely. He could start to think more about the consequences of his actions. For example, he might not rush into battles as blindly as he used to. Also, his emotional growth could be a part of it. He could become more in tune with his feelings towards his friends, especially Lucy. His loyalty to the guild could also deepen as he realizes his new form can be a great asset to protect Fairy Tail.
Her character development can be different in terms of relationships. As a female, she might be more empathetic towards other female characters in the guild, which could lead to different friendships. For example, she could form a closer bond with Lucy in a more sisterly way. In terms of her magical development, she may approach it with a different mindset. Maybe she's more cautious or strategic compared to the impulsive male Natsu. This could lead to her learning spells in a different order or mastering them in a different way.
By showing his vulnerability in the nightmare. Natsu is often seen as strong and fearless. But in a nightmare, he can be scared. This contrast can reveal his deeper emotions and fears that he usually hides.
