Well, one possibility is that Naruto would grow up with dragon - like powers. He might be able to breathe fire or have super strength. And his view of the ninja world would be very different, as he was raised in a dragon's lair rather than the Hidden Leaf Village.
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.
Eragon would probably have a different view on power. Since he was raised by dragons, he would see power as something to be respected and used sparingly, as dragons do. He may also be more fearless, as dragons are often seen as powerful and fear - inspiring creatures. His communication skills with dragons would be far superior, and he might struggle to communicate as effectively with humans.
His character would likely be more wild and free - spirited. Dragons are not bound by human rules, so Naruto might be less inclined to follow traditional ninja etiquette.
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, 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.
In a 'Harry Potter raised by dragons' fanfiction, the plot could be really exciting. Harry's upbringing by dragons would give him unique skills. For example, he might be able to understand dragon language which could hold ancient magic secrets. His moral compass could be different too, as dragons have their own code of survival. Maybe he would see the wizarding world from an outsider's perspective, since his values are shaped by the dragons.
