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?
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.
In fanfiction, Natsu's Dragon Form could be developed to have a symbiotic relationship with other characters. For example, he could combine his power with Lucy's Celestial Spirit Magic in a way that enhances both of their abilities while in his Dragon Form. This would create unique and interesting battle strategies.
One idea could be that in fanfiction, Natsu's Dragon Form could have unique fire abilities. For example, he might be able to create different shapes of fire, like a dragon made entirely of fire that can attack enemies on its own. Another could be that his Dragon Form has a connection to an ancient magic that gives him the power to heal other dragons or dragon slayers.
In fanfiction, a big theme for Kid Trunks is his role as a protector. He's always been about defending the Earth, and fan writers often expand on that. They might put him in situations where he has to make tough choices to save the planet. His friendship with the other young fighters, especially Goten, is also a popular theme. They can get into all kinds of mischief and battles together. And his Saiyan heritage is often explored, like how he discovers new abilities related to it.
One common theme is power. Since Natsu is a dragon, the fanfictions often explore the extent of his power and how he uses it. Another theme is identity. Natsu has to figure out who he is as a dragon in relation to his human side.
One popular theme could be Natsu's unrivaled strength in battles. He might effortlessly defeat powerful foes that were once considered major threats in the original story. This can create a sense of awe and admiration among other characters and readers alike.
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.
Well, 'Natsu's New Era' is quite popular. It shows Natsu leading the new generation of dragon slayers. The story is filled with his adventures as he trains the younger slayers and faces powerful enemies that threaten their world. It's a story of leadership and growth.
One of the most beloved tropes is the fusion concept. Fanfic writers might create a fusion between a Dragon Ball character and a Naruto character, and this new being has a unique way of achieving or using Ultra Instinct. It combines the best of both worlds, like the Naruto character's strategic thinking and the Dragon Ball character's raw power, all while having an understanding of Ultra Instinct that is different from the original Dragon Ball concept.
