Well, one big difference in her character development is in the area of emotions. Female Natsu might be more in touch with her emotions and express them more openly. This could lead to deeper connections with other characters but also make her more vulnerable in some situations. For instance, she might be more affected by the loss of a guildmate. In terms of her growth as a mage, she may be more interested in exploring the history and lore of magic, which was not as much of a priority for male Natsu. This newfound interest could open up different storylines for her, such as discovering ancient magic spells or artifacts that were previously overlooked by male Natsu.
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.
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.
Often, Natsu becomes more confident. With the Dragon Force, he realizes his greater potential, which boosts his self - assurance.
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.
Natsu could develop a sense of guilt. If he lost comrades during the war, he might blame himself for not being strong enough. This guilt could either drive him to become stronger or make him more withdrawn. He may also start to question his own beliefs. For instance, if he had to do some morally ambiguous things during the war to win, he'll have to grapple with the consequences of those actions.
Her character in this fanfiction could develop distinctively. Firstly, she would likely be more attuned to the darker side of the ninja world due to her Anbu work. This might make her more cynical at times. Secondly, her skills would progress in a different way. She could focus more on assassination techniques rather than the large - scale jutsu that the original Naruto was known for. This change in skill focus would also impact her personality, making her seem more aloof and mysterious, a far cry from the boisterous Naruto we know from the original series.
She might become angry at first. Natsu is known for her fiery temper. So, she could lash out at the person who betrayed her, confronting them directly and demanding an explanation.
One major difference in the portrayal of the reincarnated Fem Sephiroth compared to the original is her approach to power. The original Sephiroth was somewhat power - hungry and used it in a rather brute - force way. The fem Sephiroth could be more nuanced. She might use her power in a more diplomatic way, relying on her charm and intelligence. Additionally, her backstory as a reincarnation could give her a different perspective on life. She may have memories of her past life that haunt her, but also give her the wisdom to make different choices. This all combines to create a character that is quite distinct from the original Sephiroth.
Their relationship could develop differently if Natsu didn't initially see Zeref as an enemy. Instead of the typical animosity, Natsu could approach Zeref with curiosity. Maybe he wants to understand why Zeref created him and what his purpose really is. This could lead to a more cooperative relationship from the start.
He might become more brooding and distrustful. Banishment is a harsh experience, and Natsu, who was always so close to his Fairy Tail family, would feel betrayed. This could lead to him suppressing his emotions and becoming more solitary as he tries to figure out how to clear his name.
As they travel, their bond deepens. They start to rely on each other more. Natsu becomes more protective of Lucy, and Lucy begins to understand Natsu's impulsive nature better.
