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.
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.
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.
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.
One great 'Natsu and Lucy Dragon Cry' fanfiction could be one where they go on a special mission related to the Dragon Cry. In this fanfic, Natsu's dragon powers might be enhanced because of the Dragon Cry, and Lucy has to use all her celestial spirit magic to keep up. It could have a lot of action and their typical banter.
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.
The fanfiction might also explore their relationship in terms of growth. As they face challenges regarding the Dragon Cry, both Natsu and Lucy grow as individuals. This growth then impacts how they interact with each other. Natsu could become more understanding of Lucy's insecurities, and Lucy could become more confident in Natsu's abilities. Their relationship evolves from just being guildmates to something much deeper and more meaningful.
I highly doubt it's a popular fanfic given the rather inappropriate and unclear title. Most popular fanfics usually have more engaging and appropriate titles that give a better sense of the story.
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?
