In some fanfictions where Natsu turns into a dragon, it often gives him extraordinary power. He might have enhanced fire abilities, being able to breathe more intense flames. His physical strength could also increase exponentially, making him an even more formidable force in battles. Maybe he would also gain some dragon - like instincts, which could either help him in combat or cause some internal conflict as he tries to balance his human side with his new dragon self.
Gray would also be important. There could be a rivalry - turned - friendship aspect where Gray, who has his own ice - making powers, and Natsu, as a dragon, have to learn to work together. Maybe they compete in a friendly way to see whose powers are more useful in different situations.
In fanfiction, Natsu's dragon transformation often takes on different and exciting aspects. One common element is an enhanced physical strength that far surpasses his normal state. This allows him to take on much stronger opponents with ease. For example, in some fanfictions, he can shatter mountains with a single punch during his transformation.
One interesting plotline could be Natsu discovering new dragon powers that are unique to him. This could lead to him having to learn how to control these powers and facing challenges within the Fairy Tail guild as others may be wary or envious of his new abilities.
Yes, in a lot of Fairy Tail fanfiction, Natsu can be overpowered. Writers often like to amp up his powers for more exciting storylines. For example, they might give him new fire - based abilities or make his existing ones even stronger to defeat more powerful foes.
In fanfiction, Natsu's age can vary greatly. Some authors might keep him at his canonical age from the original Fairy Tail series, which is around 17 - 18 years old at the start. However, in alternate universe fanfictions, he could be older or younger depending on the plot. For example, in a time - travel based fanfic, he could be much older if the story takes place far into the future or much younger if it goes back to his childhood days.
One interesting concept could be exploring Natsu's new powers and abilities in the Dragon Force state in more depth. Maybe he discovers hidden techniques or ways to control the power better.
Often, it could be because of a false accusation. Maybe someone framed Natsu for a crime he didn't commit, like stealing a powerful magical artifact from the guild. So, to maintain peace and order, the guild leaders had no choice but to banish him.
One possible aspect of a Fairy Tail Natsu and Tartaros fanfiction could be Natsu's battle against the powerful foes in Tartaros. He might face new and terrifying enemies that test his limits. His dragon slayer magic would be put to the extreme, and perhaps he discovers new powers along the way.
