There might also be some human friends or allies that Natsu meets during his journey. They could be important characters as they help Natsu navigate the human world and also fight alongside him in battles.
Obviously, Natsu is one of the main characters. He is the one who was raised by dragons and his experiences and growth are central to the story.
Igneel could be one of the main dragons. Since he has a connection with Natsu in the original story, it would make sense for him to be among the dragons raising Natsu. Another could be Metalicana, as he is also a well - known dragon. Grandine might also be there, considering her importance in the Fairy Tail universe.
Well, in many fanfictions, it could be Igneel and another dragon like Metalicana. Igneel is Natsu's adoptive father in the original series, and Metalicana is Gajeel's dragon. Combining them in a fanfiction as Natsu's caretakers could lead to some really interesting character dynamics.
Obviously, Natsu is one of the main characters as it's in the title. He is likely to be the central figure around which the story revolves. There might also be other dragons that play important roles, like his dragon family members if they are introduced in the fanfiction.
Obviously Zuko is one of the main characters since he's the one being raised by the dragons.
Obviously, Natsu is one of the main characters. And then there are the twin dragons, though we don't know much about them yet from just this title. But they are sure to be important characters as they are in the 'vs' situation with Natsu.
Sometimes, an original character created by the fanfiction writer becomes the main character. This character could be an orphan who is taken in by dragons and has to learn to survive in the dragon - dominated world. Their journey of self - discovery while being raised by these mythical creatures can be a central part of the story.
The dragons that raise the twins are also key characters. They could be of different species, each with their own unique traits. For example, a Night Fury - like dragon could be very intelligent and stealthy, teaching the twins how to hunt and move quietly. And a Gronckle - type dragon might be more about brute strength, showing the twins how to stand their ground in a fight.
The dragons themselves are also important characters. There could be Toothless, who is often Hiccup's closest dragon companion in the original stories. And there might be other dragons like Stormfly, Hookfang, etc., each with their own personalities and roles in Hiccup's upbringing.
One interesting plotline could be Natsu's struggle to fit in with human society after being raised by dragons. He might have different values and ways of doing things that clash with humans.
Perhaps the plot involves Natsu having to choose between the different ideologies of the dragons that raised him. Each dragon may have its own idea about how to interact with the human world or other magical beings. This could lead to internal conflicts within Natsu as he tries to decide which path to follow. He could also use the combined knowledge from the dragons to solve a big mystery or defeat a powerful enemy that threatens both the dragon and human worlds.
