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.
In this fanfiction, the plot may center around Natsu's growth. With multiple dragons as his mentors, he grows up with a sense of unity among different dragon species. He could be on a quest to reunite the dragons who have become scattered for some reason. Along the way, he discovers secrets about his own past and the origin of the dragons, and his upbringing by multiple dragons gives him the unique ability to bridge the gap between different dragon factions.
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.
The plot could involve Natsu being sent on a special journey by the dragons for his training. Along the way, he not only masters new skills but also discovers secrets about the dragons' past and their connection to the world. He may face challenges that test his loyalty to the dragons and his own beliefs as a wizard.
Well, perhaps Natsu uses his powerful fire magic to take on the dragons one by one. He might start by finding a strategic location to face them, like on top of a large mountain where he has a better view. Then, he'd use his signature moves like Fire Dragon's Roar to blast groups of dragons at a time.
Well, it could be about Zuko learning the ways of the dragons. Maybe he discovers hidden dragon lairs and they teach him their ancient fire - bending techniques, which are different from what he's known before.
Well, one possibility is that Harry grows up with a fierce sense of independence. Dragons are known for their wild nature, so Harry might be more rebellious against the wizarding world's norms. He could have unique magical abilities learned from the dragons, like a super - strong fire - based magic.
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.
One possible plot could be that Natsu, while being raised by the female dragon, learns unique dragon magic that is different from what he would have learned otherwise. He might develop a special bond with the dragon, like a mother - son relationship, and the story could follow his adventures as he uses the skills taught by the dragon to protect the dragon's lair or the surrounding area from threats.
One possible plot could be that Natsu is raised by a dragon other than Igneel. This new dragon might have different values and teachings. For example, if it was a more reclusive dragon, Natsu might be less outgoing and more reserved compared to his canon self. The dragon could also teach Natsu different types of magic, which would change the way he fights and interacts with others in the Fairy Tail guild.
One possible plot could be that Natsu gains unique and powerful magic abilities under the tutelage of the two dragons. He might learn different combat techniques and ways to control his fire magic more precisely.
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.
