Well, in many Fairy Tail Natsu Dragon Form fanfics, we often see an expansion of Natsu's powers. Some fanfics might explore his new abilities in more detail, like how he can control different types of dragon magic that he couldn't in the original series. It's really exciting to read about his enhanced combat skills and the unique ways he uses his dragon form.
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.
Friendship and loyalty also play a big role. His friends in Fairy Tail have to accept and support him in his dragon form. In stories such as 'Bonds in Dragon Form', it shows how their relationships are tested and strengthened when Natsu reveals his dragon side.
Another aspect in fanfiction could be the relationship between Natsu's dragon form and the other characters. His friends might be in awe or even a bit scared at first when they see his new, more powerful form. For instance, Lucy could struggle to understand how much of Natsu is still himself when he transforms, and this could create some tension and interesting character development between them.
Some fanfictions focus on Natsu's dragon form and its effect on his love life. For example, how his new form affects his relationship with Lisanna or Lucy. Does his more dragon - like nature attract them in a new way? Or does it create barriers that they need to overcome?
Also, Fairy Tail has a large and dedicated fan base. People are always looking for new content related to the series. Fanfics about Natsu's dragon form fill that gap. They allow fans to experience different interpretations of the story and the character, which is something that the official series might not always be able to do.
Another plot could be that Natsu gets sent back to the past by accident while in his Dragon Cry form. Once there, he has to figure out how to get back to his own time while also dealing with the past versions of his friends and enemies. He might have to hide his true identity to avoid changing the future too much.
Another good one is 'The Dragon Within Natsu'. This fanfiction takes Natsu on a journey where his dragon form is not just a power, but a part of his identity that he has to embrace to save his guild and the world from a looming threat.
One interesting concept could be Natsu's enhanced power levels. In end form, he might have new and more powerful fire-based attacks. For example, he could create a massive inferno that not only burns but also has some kind of special effect like nullifying dark magic in the fanfiction world. Another concept could be his appearance. Maybe he has a more mature and fierce look, with his hair changing color slightly or his eyes glowing more intensely. Also, his relationships with other characters might be developed further. His bond with Lucy could become even stronger, and they could have new adventures together where his end form is crucial for their success.
Well, if Natsu travels to the past in his Dragon Cry form, he could end up teaching his younger self some new skills or ways to control his power. This could make his younger self much stronger earlier on. Also, he might encounter some long - lost dragons from the past and gain new knowledge about his dragon powers and heritage.
